Explanation:
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
