How many viral genomes are there?

Question

Classification of Viral Genomes. Currently, over 4000 viruses have been described, classified into 71 families. Even though viruses possess small genomes, they exhibit enormous diversity compared with plants, animals and even bacteria.

What are the 7 viral genomes?

The ICTV classifies viruses into seven orders: Herpesvirales, large eukaryotic double-stranded DNA viruses; Caudovirales, tailed double-stranded DNA viruses typically infecting bacteria; Ligamenvirales, linear double-stranded viruses infecting archaea; Mononegavirales, nonsegmented negative (or antisense) strand single ...

What are the 5 possible genome types for viruses?

Thus, viral nucleic acids can be DNA or RNA, double-stranded or single-stranded, monopartite or multipartite, linear or circular, as short as 2 kb or up to 2500 kb long.

What types of viral genomes exist?

The vast majority of viruses have RNA genomes. Plant viruses tend to have single-stranded RNA genomes and bacteriophages tend to have double-stranded DNA genomes. Viral genomes are circular, as in the polyomaviruses, or linear, as in the adenoviruses. The type of nucleic acid is irrelevant to the shape of the genome.
