Rank the DNA sequences according to the order in which they would denature as temperature is increased. i.e., the sequence that would be denatured at the lowest temperature would be ranked 1. For simplicity, only a single strand of each double helix is shown.
-TTTGCTGTAACTGA

Question

Quizplus · Accepted Answer

The stability of DNA sequences is influenced by the content of GC pairs, which form three hydrogen bonds, compared to AT pairs, which form two hydrogen bonds. The sequence with the highest AT content will denature at the lowest temperature due to weaker hydrogen bonding. The provided sequence, "TTTGCTGTAACTGA," has a relatively high AT content, making it less stable and likely to denature at a lower temperature compared to sequences with higher GC content. Therefore, it is ranked 1, indicating it would denature first as temperature increases.
