Vedclass · Answer

(D) According to Chargaff's rule,in a double-stranded $DNA$ molecule,the amount of Adenine $(A)$ equals the amount of Thymine $(T)$,and the amount of Guanine $(G)$ equals the amount of Cytosine $(C)$.Given: Total base pairs = $50$,so total nitrogen bases = $100$.Number of Thymine $(T)$ = $20$.Therefore,number of Adenine $(A)$ = $20$.Number of $A-T$ pairs = $20$.Number of $G-C$ pairs = Total base pairs - $A-T$ pairs = $50 - 20 = 30$.Hydrogen bonds between $A$ and $T$ = $2 	imes 20 = 40$.Hydrogen bonds between $G$ and $C$ = $3 	imes 30 = 90$.Total hydrogen bonds = $40 + 90 = 130$.
