What are the 6 different classes of virus based on their genome?

What are the different types of viral genomes?

RNA viral genomes are broadly divided into double stranded RNA, positive and negative strand single stranded RNAs, monopartite and multipartite RNA viruses. One of the primary proteins encoded by all these RNA genomes is RNA dependent RNA polymerase, essential for their replication.

What is the largest virus?

Mimivirus is the largest and most complex virus known.

Why do viruses have a small genome?

Small genome size is perfectly suited to virus replication, in which each infected host cell produces many copies of the viral genes from a single template. Such exponential replication places a premium on small genome size: the smaller the genome, the faster it can replicate.
