Show Answer
Answer:
Correct Answer: A
Solution:
- The infective constituent in viruses is actually the nucleic acid (either DNA or RNA) contained within the protein coat, not the protein coat itself. The protein coat, also known as the capsid, protects the nucleic acid and aids in the delivery of the viral genetic material into host cells, but it is the nucleic acid that carries the genetic information necessary for infection and replication.
