Question
According to the document, viruses are described as the smallest infectious agents whose genomes consist of which type(s) of nucleic acid?
Correct Answer
Option D is the correct answer.
Detailed Explanation
The document states: 'Viruses are the smallest infectious agents whose genomes consist of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) and that are absolutely dependent on living cells for their replication.' This indicates that a virus can have either DNA or RNA, but not both at once for a single species.
Hint
Recall the fundamental definition of a virus's genetic material as provided at the beginning of the 'What is a virus?' section.
