Question

Genomic nucleic acid is fragmented in

• A. $TMV$
• B. Influenza virus
• C. $HIV$
• D. Poliomyelitis virus

Answer 1

The correct option is B Influenza virus

• The influenza viruses are characterized by segmented, negative-strand RNA genomes requiring an RNA-dependent RNA polymerase of viral origin for replication.
• The particular structure of the influenza virus genome and the function of its viral proteins enable antigenic drift and antigenic shift.
• These processes result in viruses able to evade the long-term adaptive immune responses in many hosts.

So the correct answer is option B.
