Vedclass · Answer

(C) The Assertion is correct because $A-T$ base pairs are held together by two hydrogen bonds,while $G-C$ base pairs are held together by three hydrogen bonds.Because $G-C$ pairs have more hydrogen bonds,they are more stable and require more energy to break (melt) compared to $A-T$ pairs.The Reason provided is incorrect because it states the number of hydrogen bonds in reverse: $A$ and $T$ have two hydrogen bonds,while $G$ and $C$ have three hydrogen bonds.

Assertion: In a $DNA$ molecule,$A-T$ rich parts melt before $G-C$ rich parts.
Reason: In between $A$ and $T$ there are three $H-$ bonds,whereas in between $G$ and $C$ there are two $H-$ bonds.
