Final answer:
Reverse transcriptase is an HIV enzyme that synthesizes DNA from the viral RNA, not translating it into protein. HIV utilizes the CD4 receptor and CCR5 coreceptor to enter host cells, and mutations like CCR5-delta 32 provide resistance to infection. HIV-1 protease is a key target for antiviral drugs because it processes viral polyproteins.
Step-by-step explanation:
The HIV gene in question with its function seems to be mischaracterized in the student's question. The enzyme reverse transcriptase does not translate the RNA into protein; rather, it synthesizes DNA from the RNA template, a process crucial for the replication of HIV in the host cell. This enzyme allows the viral RNA to be reverse transcribed into DNA, which then can integrate into the host's genome.
Regarding the RNA-dependent RNA polymerase, this is typically a viral enzyme used by RNA viruses to replicate their RNA genome. However, HIV, being a retrovirus, primarily relies on reverse transcriptase to convert RNA to DNA, which is then incorporated into the host's genome by another enzyme known as integrase.
Discoveries like the CCR5-delta 32 mutation highlight the importance of the CD4 receptor and coreceptors such as CCR5 in the mechanism of HIV entry into host cells. Drugs targeting HIV-1 protease are also crucial in the fight against HIV, as they help to inhibit the progression of the disease by interfering with the virus' ability to process its polyproteins into functional viral components.
