Biology : Virus
Hello everybody ! Welcome to my blog again ! So glad to see you again. Before we start for new topic, you might to fill the Quiz Biology 2 about Genetics. Please send your answer to parawangsaa@yahoo.com in .docx format. Until 4 August 2014, there's no sender for the Quiz Biology 2 so don't miss the chance to improve your skills on Biology.
Okay, Let's We Start ! Now we talk about Virus. What is Virus? Virus is the living things that only can exist with the help of Host. The Virus can live everywhere, both Procaryote and Eucaryote. But, some scientist says that Virus is not a Living Things. They said that Virus is more suitable to be Grouped as a Particle that contain Genetic Substances. Virus is taken from Latin Language that mean Poison.
History Of Virus
The history of Virus began on 1883 that a Scientist from Germany, Adolf Mayer, doing a research about the cause of Mosaic Disease on the Tobacco. He Extract the leaf of tobacco mosaic disease and spray it to the healthy tobacco. After a couple of day the Healthy tobacco become Infected. But Mayer can't see anything in the leaf extration on the microscope. But Mayer still assume that this disease are caused by Bacteria.
Then in 1892, a Scientist of Russia, Dmitri Iwanowski repeat the experiment done by Meyer. The difference is only that Dmitri filter the leaf extract with the filter in such way so Bacteria can't pass it. The result is surprising, The healthy tobacco become sick too. Iwanowski assume that he doing mistake in his experiment. But Six years later a Scientist of Holland, Martinus W. Beijerinick, make sure that Dmitri didn't make any mistake in his experiment. Martinus said that The Mosaic disease is caused by filtrable virus. He said that because the vector can pass the Bacteria Filter and can't be seen in the Light Microscope. along with the invention of the Electron Microscope, Now The "Virus" can be seen.
Charateristic of Virus
The size of virus is vary from 25 - 300 nm (1 nm = 10-9 m) The smallest virus that known is Poliovirus, the virus that caused Polio Disease. It size is only 25 nm and the biggest Virus that known is Tobacco Mosaic Virus (TMV) that cause the Mosaic Disesase in Tobacco plant. Commonly virus have 4 common shape. In the Helix Shape, Polyhidris Shape, Complex and Viral Envelope.
Sturcutre And Function
Virus isn't a Cell (aseluler). Virus is a particle named virion. Virion can be crystallize so virus is more likely as mineral than living cell. As long as virus is a virion, it doesn't have cytoplasm, plasma membrane and Nukleus. Virus only have Nuclei Acid and Protein Coat.
Nuclei Acid
Mostly Virus have RNA. But it's still possible that Virus Have DNA.
Protein Coat (Capsid)
Capsid is made of the protein subunit called Capsomer. Capsid is also act as skeleton of the virus.
Reproduction of Virus
Virus have an ability that only living cell can do it. Virus can multiply itself, But need a help from a host than this process will broke up the cell. Hereby the process of Virus Reproduction.
Virus Type
Bacteria Virus
The virus that the host is a bacteria. The Bacteria virus is also known as Bacteriophage. Example. Bacteriophage T4 that having E.coli as a host.
Plant Virus
The virus that the host is a plant cell. Mostly the Plant virus only have RNA Nuclei Acid. The example is TMV that caused Mosaic Disease in Tobacco Plantts
Eucaryote Microorganism Virus
The virus that the host is an eucaryote cell but only can seen by Microscope. The example is Mycovirus that infected Fungi
Animal Virus
The virus that the host is an animal cell / human cell. Animal virus mostly have DNA Nuclei Acid. The Example is Rabies in the Canis Genus.
The Advantage of Virus.
Virus in our life isn't always harm us. Virus Can be act as Gene Agent for human interest. Example in Producing Pestisides or Producing Medicines.
Virus that Harming Human
The Harming Virus
Mostly virus are harm for our life. Here's the list of Harming Virus :
- Influenza Virus
Influenza virus is the virus that Caused Influenza. If the patient is ignored, that can be lead to Acute Respiratory Syndrome or in Indonesia commonly said ISPA. The symptomps are fever, cold, headache, backache, and coughing. Influenza is quiet tough to cure because the Mutation speed are very high.
- HIV (Human Immunodificiency Virus)
HIV is the Retrovirus that break down our immune system by attacking The T-helper Cell. Until now there has been no Medicine that stong enough to beat HIV because HIV is hiding in the T-Helper cell.
-Hepatitis Virus
Hepatitis Virus is the virus that caused Hepatitis B. This virus attacking the liver cell so lead to yellow fever and abdominal disorders.
-Ebola Virus
Ebola virus is the virus that caused Ebola Disease that grew up in the Continent of Africa. The Symptomps is the fever with severe bleeding that can lead to Dead.
-Measles Virus
Measles Virus is the Virus that causes Measles. This virus attack skin cell and causes early symptomps like fever, coughing, cold, than appear Measles wound from the face until to every part of the body.
-Polio Virus
Polio Virus is the virus that causes Polio. Polio Virus attacked Nerve cell that lead to paralyzed. Many Public figure that was suffer this Disease ex. Franklin Delano Roosevelt, The 26th President of USA.
- Mumps Virus
Mumps virus is the virus that Causes Mumps. Mumps is the disorder in the saliva gland that lead to oedema at the behind of the ears.
- Herpes Simplex Virus
This virus causes Herpes. Herpes is the disease that attacked skin cell and Mucus membrane on the mouth that cause flushed skin and appear nodule that like blister
- Human Papilloma Virus (HPV)
HPV is the virus that causes Herpes. Herpes is the disease that attacked skin cell and grow to cancer cell. The symptoms is the nodule in the skin
Virus that harm Animal
- Rous Sarcoma Virus (RSV) that caused tumours in the chicken
-Newcastle Disease that causes tetelo in the chicken
-Rhabdovirus, that caused rabies in Canis Genus with symptomps scared of water, big anxiousity, lost the control of the muscle and more Aggresive
Virus that Harm Plants
-Tobacco Mosaic Virus (TMV) that caused Mosaic disease that inhibited the growth of the plants and appearing spotting on the Tobacco leaves.
-Citrus leprosis Virus (CiLV) that causes inhibition in the Orange plants
Prevention against Virus attack
-Immunization when still baby
The list of the immunization
1)OPV (Oral Polio Vaccine)
2)Rabies Vaccine
3)Hepatitis Vaccine
4)Influenza Vaccine
5) Mumps, Measles, Rubella Vaccine
Okay, That's all about Virus, if you have any questions, feel free to ask to parawangsaa@yahoo.com. I'm Waiting ! See ya Guys !!!

Biology : Pattern of Heredity (End)
In this post I will discuss more about the genetics. So far we have discussed the Mendel's Law and Deviations intercede. So this time I will discuss further on the Application of Genetics in the life science and Some Genetic Diseases known to solving tips Genetics with Fast and Right.
Links and Move Cross
Links and Jump Cross is also regarded as a deviation of Law Moot Mendel. The reason is the number of genes far more with the number of chromosomes. For example Humans have 23 pairs of chromosomes that have more than 40,000 genes. Therefore, many of the genes in each chromosome. Two chromosomes on homologous chromosomes carry one allele for each gene. Homologous chromosomes with alleles that are therein experiencing separation during meiosis independently according to Mendel's Law of Segregation. In contrast, alleles of different genes located on the same chromosome do not follow Mendel's law of segregation II Freely. Genes are experiencing Links. Links are the terms on which a gene is not genetic berpiasah freely. Links can occur in the genital and chromosome non-sex chromosomes.
Autosomal link
Link events observed intensively observed by Thomas Hunt Morgan with media Fruit Flies (Drosophilla melanogaster). Fruit flies are used because they are easy to breed and have a short generation time. Morgan discovered a white-eyed male fruit flies and winged wrinkles which he considers to be a mutant. Morgan considers this as a recessive mutant flies that carried out a test among females wildype Cross (wild) with a white-eyed males winged wrinkles. Morgan expects a comparison between wildtype: vestiglal gray: black normal: mutant = 1: 1: 1: 1, but the results are far from expectations Morgan.
Gonosomal link
After Morgan discovered a white-eyed male fruit flies, he marry at a red-eyed female fruit flies. The result in all the F1 red-eyed offspring. Then F1 allowed to marry each other. The results showed that all red-eyed female fruit fly and a half of white male fruit flies with phenotype ratio of 3: 1 The interesting thing about this experiment is the white eye color is only found in male fruit flies. Morgan drew the conclusion that the white eye gene is X chromosome linked
sex-linked genes are genes that are located on the sex chromosomes and the nature of the induced genes on this chromosome derived along with gender. Sex chromosome consisting of chromosomes X and Y. Women have XX chromosome composition and arrangement Males have XY chromosomes. Between the X chromosome and the Y chromosome are homologous and non-homologous parts. Part homologous on the X chromosome and the Y chromosome is the part where X and Y have the same arrangement of genes. As for the non-homologous on the X chromosome and the Y chromosome is the part where between X and Y is absolutely no similarity in the composition of genes. Genes link is divided into 2 types, namely Imperfect Genes linked (X chromosome linked gene) and Perfect Genes Linked (Linked Gen Y chromosome).
X Chromosome Genes Linked
X Chromosome Genes Linked called link is not perfect because the female sex chromosome composition XX law giving rise to dominance and recessive traits are determined by genes linked Hence X chromosome, usually the X chromosome linked trait commonly expressed by-The entrepreneurs men. For example, color blindness and hemophilia
Gen Y Chromosome Linked
Gen Y Chromosome Linked called perfect link. Y chromosome linked gene and the properties of the resulting so-called holandrik nature, meaning they can only be derived trait in men. Genes on the Y chromosome is very rare and will only be lowered if lowered in men. Examples are Hyperthrichosis (hair growing in the ear canal).
moving Cross
Crossing over is the event peetukaran a chromatid genes with genes homologous chromatids. usually occurs in Prophase phase in cell division.
To determine the percentage of used Crossover Formula
Classification of Human Blood.
1) ABO System
Case example:
A Mother's blood group AB blood group married to a heterozygous father. What is the percentage of children who will be born with blood group B?
P1: IAIB> <IAI
G: IA, IB> <IA, i
<Sorry, Can not Published Photos>
F1: IAIA, IAI, IAIB, IBI
B = 25%
2) MN System
3) Rhesus System
A study says that almost all Asians have Rh + phenotype while 90% Europeans have Rhesus phenotypes -. Therefore, marriage between men and women is difficult to conceive of Europe due to disorder, commonly called Erythroblastosis fetalis.
Sex determination
Human - Male = 44 + XY
- Women = 44 + XX
Insects - Males = 22 + X
- Females = 22 + XX
Aves - Males = 38 + ZZ
- Females = 38 + ZW
Bees - Males = Haploid (16)
- Females = diploid (32)
Type Abnormalities and Genetic Disease
Autosomal recessive
- Albino = no skin pigment (melanin)
- Sickle Cell = The sickle-shaped red blood cells
- Cystic Fibrosis = absence of protein channels for chloride ion pathway leading to mucus in the respiratory
- Phenylketonuria (PKU) = The lack of an enzyme that breaks down phenylalanine that accumulate in the body and result in mental retardation
- Galactosemia = absence of an enzyme that breaks Galactose-1-phosphate into glucose-1-phosphate so that galactose accumulate in the body and can cause mental retardation
- Thalassemia = Form of abnormal blood cells and lead to anemia
- Xeroderma pigmentosum disorder = pigment in the skin that lead to skin cancer
Autosomal dominant
- Achondroplasia = abnormal growth of cartilage that causes stunted
- Braktidaktili = Shortening of finger segments
- Polidaktili = Growth radius excess
- Hungtinton = degeneration of the nervous system that is fast and irreversible
- Progeria = Premature aging
Linked recessive X chromosome
-Buta Color
-Ichtyosis = Steroid sulfatase enzyme deficiency, causing dry and rough skin
-Distrofi Muscle protein dystrophin = deficiency that causes muscle degeneration and mental retardation
Difficult -Hemofilia = Blood clot and trigger severe bleeding
Number of Chromosome Aberration
- Normal XYY = no symptoms and can only be detected by karyotype Compilation
- = Down Syndrome, mental retardation, heart defects and sterile
- = Sterile Klinefelter Syndrome, mental retardation, female secondary sex characteristics Appear
- Turner Syndrome = Sterile
Structure of Chromosome Aberration
- Cri Du Chat Syndrome = mental retardation and abnormal shape of the larynx
Okay, that was the in-depth discussion on Genetics. Because hard enough to enter a number of media genetics. I opened up the opportunity for readers to ask about genetics to parawangsaa@yahoo.com. And do not forget tomorrow I will hold Biology Quiz 2 Prepare yourself and Regards Biology !!!

Okay, that was the in-depth discussion on Genetics. Because hard enough to enter a number of media genetics. I opened up the opportunity for readers to ask about genetics to parawangsaa@yahoo.com. And do not forget tomorrow I will hold Biology Quiz 2 Prepare yourself and Regards Biology !!!
Biologi : Genetika (Selesai)
Dalam post ini saya akan membahas lebih dalam mengenai genetika. Sejauh ini kita telah membahas Hukum Mendel dan Penyimpangan Semunya. Maka kali ini saya akan membahas lebih jauh mengenai Penerapan Ilmu Genetika dalam kehidupan dan Beberapa Penyakit Genetika yang terkenal hingga tips-tips menyelesaikan soal Genetika dengan Cepat dan Tepat.
Tautan dan Pindah Silang
Tautan dan Pindah Silang juga dianggap sebagai Penyimpangan Semu Hukum Mendel. Penyebabnya adalah Jumlah gen yang Jauh lebih banyak dengan Jumlah Kromosom. Misalnya Manusia yang memiliki 23 pasang Kromosom memiliki lebih dari 40.000 jenis gen. Oleh karenanya banyak gen dalam tiap kromosom. Dua Kromosom pada kromosom homolog membawa satu alel untuk tiap gen. Kromosom Homolog dengan alel-alel yang berada didalamnya mengalami pemisahan secara secara bebas pada saat meiosis sesuai dengan Hukum Mendel mengenai Segregasi. Sebaliknya, alel-alel dari gen-gen yang berbeda yang terletak pada satu kromosom yang sama tidak mengikuti Hukum II Mendel mengenai pemisahan Secara Bebas. Gen-gen tersebut mengalami Tautan. Tautan adalah istilah pada genetika dimana suatu gen tidak berpiasah secara bebas. Tautan dapat terjadi pada Kromosom kelamin maupun kromosom non-kelamin.
Tautan Autosomal
Peristiwa tautan diamati secara intensif diamati oleh Thomas Hunt Morgan dengan media Lalat Buah (Drosophilla melanogaster). Digunakan Lalat buah karena mudah berkembang biak dan punya waktu generasi yang singkat. Morgan menemukan suatu lalat buah jantan bermata putih dan bersayap keriput yang dia anggap sebagai mutan. Morgan menganggap lalat mutan ini sebagai resesif sehingga dilakukan test Cross antara Betina wildype (liar) dengan jantan bermata putih bersayap keriput. Morgan mengharapkan perbandingan antara wildtype : abu-abu vestiglal : hitam normal : mutan = 1 : 1 : 1 : 1. Tetapi hasilnya jauh dari harapan Morgan.
Tautan Gonosomal
Setelah Morgan menemukan lalat buah jantan bermata putih, ia mengawinkannya pada seekor lalat buah betina bermata merah. Hasilnya pada F1 semua keturunannya bermata merah. Lalu F1 dibiarkan mengawini sesamanya. Hasilnya diperoleh bahwa Semua lalat buah betina bermata merah dan setengah dari lalat buah jantan berwarna putih dengan rasio fenotipe 3 : 1. Hal yang menarik dari percobaan ini adalah warna mata putih hanya terdapat pada lalat buah jantan. Morgan menarik kesimpulan bahwa gen mata putih merupakan tertaut kromosom X.
Gen Tertaut Kelamin (sex linked genes) adalah gen yang terletak pada kromosom kelamin dan sifat yang ditimbulkan gen pada kromosom ini diturunkan bersama dengan jenis kelamin. Kromosom kelamin terdiri dari kromosom X dan Y. Perempuan memiliki susunan Kromosom XX dan Laki-laki memiliki susunan Kromosom XY. Antara kromosom X dan kromosom Y terdapat bagian yang homolog dan bagian yang tidak homolog. Bagian homolog pada kromosom X dan Y adalah bagian dimana kromosom X dan Y memiliki susunan gen yang sama. Sedangkan untuk bagian non-homolog pada kromosom X dan Y adalah bagian dimana diantara kromosom X dan Y sama sekali tidak ada persamaan pada susunan gennya. Gen tautan terbagi menjadi 2 jenis, yaitu Gen tertaut Tidak Sempurna (Gen tertaut kromosom X) dan Gen Tertaut Sempurna (Gen Tertaut Kromosom Y).
Gen Tertaut Kromosom X
Gen Tertaut Kromosom X disebut tautan tidak sempurna karena pada perempuan susunan kromosom kelaminnya XX sehingga menimbulkan hukum dominansi dan resesif bagi sifat-sifat yang ditentukan oleh gen-gen tertaut kromosom X. Oleh karena itulah, biasanya sifat tertaut Kromosom X biasa diekspresikan oleh-laki-laki. Contohnya Buta Warna dan Hemofilia
Gen Tertaut Kromosom Y
Gen Tertaut Kromosom Y disebut tautan sempurna. Gen tertaut kromosom Y dan sifat-sifat yang ditimbulkannya disebut sifat holandrik, berarti sifat tersebut hanya dapat diturunkan pada laki-laki. Gen pada kromosom Y sangat langka dan kalaupun diturunkan hanya akan diturunkan pada laki-laki. Contohnya adalah Hyperthrichosis (tumbuh rambut pada saluran telinga).
Pindah Silang
Pindah silang adalah peristiwa peetukaran gen-gen suatu kromatid dengan gen-gen kromatid homolognya. biasanya terjadi pada fase Profase dalam pembelahan sel.
Untuk menentukan persentase Pindah silang digunakan Rumus
Penggolongan Darah Manusia.
1) Sistem ABO
Contoh Kasus :
Seorang Ibu bergolongan darah AB menikah dengan Ayah bergolongan darah A heterozigot. Berapa Persentase anak yang akan dilahirkan dengan golonag darah B?
P1 : IAIB >< IAi
G : IA , IB >< IA , i
<Maaf, Foto tidak Dapat Ditampilkan>
F1 : IAIA, IAi, IAIB, IBi
B = 25 %
Golongan Darah MN
Gologan Darah Rhesus
Suatu Studi menyebutkan bahwa hampir semua orang Asia berfenotipe Rh + sedangkan 90 % Orang Eropa berfenotipe Rhesus - . Oleh karena itu perkawinan antara laki-laki dan wanita eropa sulit memperoleh keturunan dikaibatkan kelainan yang lazim disebut Erythroblastosis Fetalis.
Determinasi Seks
Manusia - Laki-laki = 44 + XY
- Perempuan = 44 + XX
Serangga - Jantan = 22 + X
- Betina = 22 + XX
Aves - Jantan = 38 + ZZ
- Betina = 38 + ZW
Lebah - Jantan = Haploid (16)
- Betina = Diploid (32)
Jenis Kelainan dan Penyakit Genetik
Resesif Autosomal
- Albino = tidak ada pigmen kulit (melanin)
- Sickle Cell = sel darah merah berbentuk Sabit
- Fibrosis Sistik = Tidak adanya saluran protein untuk jalur ion Klorida sehingga menimbulkan lendir di daerah pernafasan
- Phenylketonuria (PKU) = Tidak adanya enzim yang memecah fenilalanin sehingga menumpuk pada tubuh dan mengakibatkan keterbelakangan mental
- Galaktosemia = Tidak adanya enzim yang memecah Galaktosa-1-Fosfat menjadi Glukosa-1-Fosfat sehingga galaktosa tertumpuk pada tubuh dan dapat menyebabkan keterbelakangan mental
- Thalasemia = Bentuk sel darah yang abnormal dan berujung pada anemia
- Xeroderma pigmentosum = kelainan pigmen pada kulit yang berujung pada kanker kulit
Dominan Autosomal
- Akondroplasia = pertumbuhan abnormal tulang rawan yang menyebabkan kerdil
- Braktidaktili = Pemendekan ruas-ruas jari
- Polidaktili = Pertumbuhan jari-jari yang berlebih
- Hungtinton = Degenerasi sistem saraf yang cepat dan irreversibel
- Progeria = Penuaan dini

-Distrofi Otot = Defisiensi protein Distrofin yang menyebabkan degenerasi otot dan keterbelakangan mental
-Hemofilia = Darah sukar membeku dan memicu pendarahan hebat
Aberasi Jumlah Kromosom
- XYY = Normal tanpa gejala dan hanya bisa dideteksi dengan Penyusunan Kariotipe
- Syndrome Down = Keterbelakangan mental, steril dan cacat jantung
- Syndrome Klinefelter = Steril, Keterbelakangan mental, Muncul ciri seks sekunder perempuan
- Syndrome Turner = Steril
Aberasi Struktur Kromosom
- Syndrome Cri Du Chat = keterbelakangan mental dan bentuk laring abnormal
Oke, itu tadi adalah pembahasan mendalam mengenai Genetika. Berhubung Cukup sulit memasukkan sejumlah media genetika. Saya membuka kesempatan bagi readers untuk bertanya seputar Genetika ke parawangsaa@yahoo.com. Dan jangan lupa besok saya akan mengadakan Kuis Biologi 2. Persiapkan dirimu dan Salam Biologi !!!
