You are studying a bacterial virus and found its base composition to be `A=22%,T=28%,G=20%` and `C=30%` . What is your conclusion regarding its genetic material ?

A

Single stranded RNA

B

Double stranded RNA

C

Single stranded DNA

D

Double stranded DNA

Text Solution

Verified by Experts

The correct Answer is:
C
Double-helical DNA would have a base composition in which A=T and G=C. Thid DNA does not, thus virus must not have double -stranded DNA as its genetical material
