Final answer:
HIV is a retrovirus that uses reverse transcriptase to transcribe its RNA into DNA, allowing it to integrate into the host cell's genome, replicate, and spread rapidly.
Step-by-step explanation:
HIV as a Retrovirus
HIV (Human Immunodeficiency Virus), which causes AIDS, is classified as a retrovirus. Retroviruses are unique among RNA viruses because they reverse the usual flow of genetic information from DNA to RNA by using a special enzyme called reverse transcriptase. After entering a host cell, HIV uses reverse transcriptase to convert its RNA into DNA, which then becomes integrated into the host cell's own DNA. This allows HIV to reproduce inside the host's cells and is a key factor in the rapid spread of the virus within the human body, as it targets crucial immune system cells known as CD4+ T cells.
The drugs to treat AIDS often aim to inhibit the action of the HIV reverse transcriptase, thereby blocking further replication of the virus. Understanding the mechanism of action for HIV is essential for developing treatments and preventative strategies to combat the ongoing HIV/AIDS pandemic.
