The amount of purines and pyrimidines is equal.

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).

Column $I$	Column $II$
$(A) 5386$ nucleotides	$(p) E. coli$
$(B) 48502$ bp	$(q) \text{Man}$
$(C) 4.6 \times 10^6$ bp	$(r) \text{Drosophila}$
$(D) 3.3 \times 10^9$ bp	$(s) \phi \times 174 \text{ bacteriophage}$
	$(t) \text{Bacteriophage lambda}$
