Virus de ARN: Diferenzas entre revisións

The evolution of the picornaviruses based on an analysis of their RNA polymerases and [[helicase]]s appears to date to the divergence of the [[eukaryote]]s.<ref name=Koonin2008>Koonin EV, Wolf YI, Nagasaki K, Dolja VV (2008) The Big Bang of picorna-like virus evolution antedates the radiation of eukaryotic supergroups. Nat Rev Microbiol 6(12):925-939</ref> Their putative ancestors include the bacterial group II [[retroelement]]s, the family of HtrA [[protease]]s and DNA [[bacteriophage]]s.
