When HIV attack upon its host target cell:
a) Its RNA genome is broken down immediately
b) Its RNA genome is replicated first and then broken down
c) Its RNA genome is converted into viral DNA first and then broken down
d) Its RNA genome immediately causes breakdown of host DNA
ANSWER:
The correct option is (c)
EXPLANATION:
When HIV attacks its host target cell, its RNA genome is converted into viral DNA first and then integrated into the host cell's DNA by the viral enzyme called integrase. This allows the viral DNA to be replicated along with the host cell's DNA. The viral DNA may remain latent or become active, leading to the production of new viral particles that can infect other cells. Therefore, the correct option is (c) Its RNA genome is converted into viral DNA first and then broken down.

Answer:
please mark me as a brainlist
Explanation:
Your explanation is mostly correct, but there is a minor correction needed in the last part of your explanation.
When HIV attacks its host target cell, its RNA genome is indeed converted into viral DNA first and then integrated into the host cell's DNA by the viral enzyme integrase. However, the viral RNA is not broken down after this process. Instead, it becomes a permanent part of the host cell's genetic material as a provirus.
The correct option is still (c) - "Its RNA genome is converted into viral DNA first and then integrated into the host cell's DNA."
