What is the background of HIV?
Scientists believe that HIV originally came from a virus particular to chimpanzees in West Africa during the 1930s, and originally transmitted to humans through the transfer of blood through hunting. Over the decades, the virus spread through Africa, and to other parts of the world.
What is replication in HIV?
Replication is the process to make new copies. The HIV virus only replicate in human cells. The HIV replication process carrying seven steps, the steps are entry, reverse transcription, integration, transcription, translation, assembly, release and maturation.
What is the major site of HIV replication?
The gut-associated lymphoid tissue: a major site of HIV replication and CD4 cell loss.
What is the cycle of HIV replication?
HIV Replication Cycle. This infographic illustrates the HIV replication cycle, which begins when HIV fuses with the surface of the host cell. A capsid containing the virus’s genome and proteins then enters the cell. The shell of the capsid disintegrates and the HIV protein called reverse transcriptase transcribes the viral RNA into DNA.
What is the basic concept of viral replication?
Viral Replication: Basic Concepts Viruses are obligate intracellular parasites Viruses carry their genome (RNA or DNA) and sometimes functional proteins required for early steps in replication cycle Viruses depend on host cell machinery to complete replication cycle and must commandeer that machinery to successfully replicate
How does HIV infect the cell membrane?
A capsid containing the virus’s genome and proteins then enters the cell. The shell of the capsid disintegrates and the HIV protein called reverse transcriptase transcribes the viral RNA into DNA.
How does the AIDS virus work?
HIV virus locates & destroys CD4 or T cells-white blood cells that help fight disease. The virus takes over the cell using it to replicate itself. What is AIDS?
