So if A 20%, the Tru4tbe 20% 2a. 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 20% A, 20% G,30% C, and 3026T. Based on this information, would you report that you have isolated a virus with a single-stranded DNAlgenome, double-stranded DNA genome, or single-stranded RNA genome? Explain. l4 pts!Anwhqntrovad A Virua Moun ditb blw DNA t+RNA IS Thymine s in DNA, but Ades 2b. While studying the structure of a small gene that was sequenced during the Human Genome Project, your colleague notices that one strand of the DNA molecule contains 20 A's, 25G's, 30 C's, and 22 T's. How many of each base is found in the complete double stranded molecule? Show your calculation. ( pts) 2

Explanation / Answer

We know that in DNA A is pair with T and G with C or vice versa.
We have single strand with 20A, 25G, 30C and 22T.
That measn A pair with T and G pair with C
=20A to 20T,
25G to 25C,
30C to 30G
And 22T to 22A
Let's sum all A,T,G and C
Total A = 22+20=42
T=22+ 20=42
C= 30+25=55
G=30+25=55
In given double strand DNA may contain 55C,55G,42A and 42T
