Question

what is the etiology of HIV?

Answer 1

HIV virus is proved to destroy CD4 cells or T cells of our body, which are the important component of the immune system. The HIV infection starts when a virion is attached to the affected host cell. More specifically by the action on the CCR5 and CXCR4 receptors of HIV-1. Further there is replication of the viral DNA/RNA, followed by the transcription into mRNA. And it is proved that the HIV is RNA based retrovirus which utilizes, reverse transcription reaction means RNA is converted into DNA, followed by the transcription to generate mRNA, which is then translocated into the host cell ribosomes. As a result the viral proteins are synthesized in the host cell governing the whole genome of the host.
