Why would a drug that damages capsids help treat a viral infection?
Natasha_Volkova [10]

The correct answer is D. Without capsids, viruses could not replicate

Explanation:

A viral infection is caused as a virus enters the body and this replicates inside it by using the host's cells. This is possible through the capsid which is an external layer in the virus that provides protection to it and helps the virus replicate because the capsid is essential for the virus to attach and penetrate the host's cells to replicate. According to this, if a drug damages the capsids the virus could not replicate and this should or reduce the infection caused by the virus. Thus, a drug that damages capsids helps treat a viral infection because "without capsids, viruses could not replicate".
