1st attempt A segmented viral genome Choose one: A. is packaged at random into new virion particles. B. can only occur in viruses with DNA genomes. C. fragments into nucleotides after infection. D. can facilitate rapid evolution of new viral strains.

A segmented viral genome can facilitate rapid evolution of new viral strains.

Explanation:

The genome of the virus contains both coding and non-coding sequences. Segmented viral genomes are separate unit of nucleic acid in a virion particle and they undergo reassortment.

When the genome of the viral DNA gets segmented, the multiple DNA strands. When two infection with 2 strands of virus takes place simultaneously the two strains may get swapped or cross over. This leads to new strand and hence evolution happens.

examples of such virus are : Birnaviradae, reoviridae
