AT-Rich DNA Will Denature/melt

Question

AT-rich DNA will denature/melt
A) at a higher temperature than GC-rich DNA.
B) at a lower temperature than GC-rich DNA.
C) usually at the same temperature as GC-rich DNA, with some minor variations.
D) in accordance with the animal or plant from which it was taken.

Accepted Answer

AT-rich DNA has fewer hydrogen bonds, which makes it easier to denature or melt than GC-rich DNA. Therefore, it will denature/melt at a lower temperature than GC-rich DNA.
