Question

(B) When $DNA$ is heated,the hydrogen bonds between the complementary base pairs break,causing the double helix to denature or melt. $G-C$ base pairs

Vedclass · Accepted Answer

$G : C$ ratio

Vedclass · Answer

(B) When $DNA$ is heated,the hydrogen bonds between the complementary base pairs break,causing the double helix to denature or melt. $G-C$ base pairs are held together by three hydrogen bonds,whereas $A-T$ base pairs are held together by only two hydrogen bonds. Therefore,$DNA$ molecules with a higher $G : C$ content require more energy (higher temperature) to denature. By comparing the $G : C$ ratio,one can determine the thermal stability and the extent of denaturation of $DNA$ samples.
