Virus bases: humans have 3 billion bases, or nucleotides, in our genome. In comparison, a typical virus has approximate 50,000 bases: this is very small. In recent years, some very large viruses have been found: the megavius and mimivirus, double stranded dna, 1. 2 million bases. 10-5-16: approximately 400 nm, pandoravirus, largest known virus, 1. 9 2. 5 million bases. The cell is sometimes destroyed in this process. Increases in mutations; unique viral lineages: consequently, there was an increase in patients.
