Question

Quizplus · Accepted Answer

The structure indicated by the given nucleotide counts (10A, 15T, 3G, 7C) is single-stranded DNA (ssDNA). This is because DNA contains thymine (T), whereas RNA contains uracil (U) instead of thymine. The presence of thymine and the lack of uracil suggest it's DNA, not RNA. The counts of adenine (A) and thymine (T) do not match the counts of guanine (G) and cytosine (C), which suggests it is single-stranded, as double-stranded DNA would have complementary base pairing (A with T, G with C) in equal amounts.
