A) A single-stranded DNA virus
B) A double-stranded DNA virus
C) A single-stranded RNA virus
D) A double-stranded RNA virus
Correct Answer: D
Solution :
The presence of U indicates a RNA virus. A and G are purines while U and C are pyrimidines. When ratio of purines: pyrimidines = 1, this suggests that there is complementary base pairing between the bases. Thus, this must be double-stranded ENA virus.You need to login to perform this action.
