Vedclass · Answer

(C) According to $Chargaff's$ rule,in a double-stranded $DNA$ molecule,the amount of purines $(Adenine + Guanine)$ is always equal to the amount of pyrimidines $(Thymine + Cytosine)$.This is because $Adenine$ always pairs with $Thymine$ and $Guanine$ always pairs with $Cytosine$ through hydrogen bonds.Therefore,the ratio of purines to pyrimidines is always $1:1$,regardless of the total number of nucleotides ($77$ in this case).
