WebJun 23, 2006 · Despite the apparent importance of RNA viruses to marine organisms, almost nothing is known about natural communities of RNA viruses in the sea. The most tantalizing evidence that the diversity of RNA viruses in the sea extends well beyond what has been revealed in culture comes from a study that used gene-specific primers to target … WebAug 13, 2024 · Competing interests: The author has declared that no competing interests exist. RNA viruses have high mutation rates—up to a million times higher than their hosts—and these high rates are correlated with enhanced virulence and evolvability, traits considered beneficial for viruses. However, their mutation rates are almost disastrously …
