Question

Select the right sequence regarding replication of HIV in a cell.

• A. I --- II --- III --- IV --- V
• B. II --- III --- IV --- I --- V
• C. II --- I --- III --- IV --- V
• D. V --- II --- I --- III --- IV

Answer 1

The correct option is A I --- II --- III --- IV --- V

When a virus attacks a cell, it starts replicating using the cell's machinery. In the case of a virus with RNA as its genome such as HIV, it undergoes reverse transcription to form viral DNA. The viral DNA gets incorporated in the host cell's DNA. During the normal transcription and translation of the host DNA, viral RNA and viral proteins (envelope, capsid, enzymes) are synthesised and as result, copies of viruses are released from the infected cell.
