When looking at a single-stranded piece of DNA,

Question

Quizplus · Accepted Answer

Because a single-stranded piece of DNA only has one strand, it cannot form Watson-Crick base pairs (G-C or A-T). Therefore, G can be next to T in a single-stranded piece of DNA. Option A is incorrect because G can also be paired with A in a single-stranded piece of DNA. Option B is incorrect because it suggests that there are two G's in a row, which is not possible in a single-stranded piece of DNA. Option D is incorrect because G can be next to A in a single-stranded piece of DNA.
