Question

Viral genes are made up of ______.

Options

• DNA only

• RNA only

• either DNA or RNA

• either proteins or nucleic acids

Answer 1

Viral genes are made up of either DNA or RNA.

Explanation:

Viral genes are unique because they can be composed of either deoxyribonucleic acid (DNA) or ribonucleic acid (RNA), but almost never both in the same virus particle. While all cellular life forms use DNA as their primary genetic blueprint, viruses are highly diverse and can store their genetic information in various forms, such as single-stranded or double-stranded DNA or RNA. This genetic material is typically encased in a protective protein shell called a capsid.
