You are a virologist interested in studying the evolution of viral genomes. you are studying two newly isolated viral strains and have sequenced their genomes. you find that the genome of strain 1 contains 25% a, 55% g, 20% c, and 10% t. you report that you have isolated a virus with a single-stranded dna genome. based on what evidence can you make this conclusion? aa. single-stranded genomes always have a large percentage of purinesb. using the formula: g - a = c + tc. double-stranded genomes have equal amounts of a and td. single-stranded genomes have a higher rate of mutation
