You are a virologist interested in studying the evolution of viral genomes. You are studying two newly isolated viral strains an
d 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
Answer: Double stranded genomes have equal amounts of A and T. Explanation:
In a DNA double helix, the complementary nucleotides must be equal otherwise it would cause staggering A and T must be equal to each other as C and G must be equal to each other.
The base pairs need not to be in the same ratios - i.e. A-T and C-G base pairs do not have to equal each other
Yes because genetic testing will provide enough evidice for the genetic disease. If you do so you can find diseases before they have long lasting effects on the hosts body
