The genome of influenza virus is made up of _.
Correct answer: A. Single strand RNA
- A. Single strand RNA
- B. Double strand DNA
- C. Single strand DNA
- D. Double stranded RNA
Explanation
Influenza viruses, belonging to the Orthomyxoviridae family, have a segmented, negative-sense, single-stranded RNA genome. The genome consists of multiple RNA segments, typically eight in the case of influenza A and B viruses. The negative-sense RNA requires the virus to carry its own RNA-dependent RNA polymerase to transcribe it into positive-sense RNA, which can then be used for protein synthesis.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
