what is the viral genome, Target cells,course of infection and Prognosis of HIV?
Homework Answers
HIV: Human Immunodeficiency Virus.
It is a retrovirus.Its genome consists of two identical single strandard RNA molecules.
HIV genome consists of nine genes in this out 6 are regulatory genes where as remaining 3 are genes which are important for reproduction and infection.
TARGET CELLS.
HIV virus specifically targets T helper cells.It also targets microphages and microglial cells.
COURSE OF INFECTION.
There are stages in HIV infection.
Acute HIV infection which is after 2-4 weeks of infection.People see flu like symptoms.
Clinical latency period in which the HIV becomes somewhat dormant and reproduce at low levels.
AIDS is a stage which is dangerous and immune system of the peopel will be completely damaged and they are prone to oppurtunistic diseases.
PROGNOSIS OF HIV.
HIV becomes to AIDS in ten years without treatment and dies within 3 years after he enters into AIDS.
Mostly with treatment in early infection stage a person can live upto 50 years.

To promote the translational activity of ribosomes in human cells for synthesizing viral proteins during infection,...
To promote the translational activity of ribosomes in human cells for synthesizing viral proteins during infection, viruses: a)Keep a ribosome binding site specific to human ribosomes on their genome. b)Only adhere to and infect metabolically active host cells where protein synthesis is high. c)Maintain introns and sometimes exons in there genomes to appear as eukaryotic mRNA. d)Chemically modify (e.g., cap and methylate) the transcripts.
