Question

Genome of the virus is

• A. DNA
• B. RNA
• C. DNA \& RNA
• D. DNA or RNA

Hint:

Viral genomes consist of either DNA or RNA, not both.

Answer 1

The Correct Option is D

Viruses are unique infectious agents that contain genetic material in the form of either DNA or RNA, but not both simultaneously. The viral genome carries the information necessary for replication and production of viral proteins within a host cell. Depending on the type of virus, the genome can be single-stranded or double-stranded, linear or circular. For example, bacteriophages often have double-stranded DNA genomes, whereas retroviruses like HIV have single-stranded RNA genomes. This distinction is fundamental in virology because it affects the replication mechanisms and classification of viruses.
