Vedclass · Answer

(D) According to Chargaff's rule,in a double-stranded $DNA$ molecule,the amount of adenine $(A)$ is equal to thymine $(T)$,and the amount of guanine $(G)$ is equal to cytosine $(C)$.Given: $G = 75$,therefore $C = 75$.Given: $T = 75$,therefore $A = 75$.The total number of nucleotides in the $DNA$ segment is the sum of all four nitrogenous bases: $A + T + G + C = 75 + 75 + 75 + 75 = 300$.

In a given $DNA$ segment,the number of nucleotides of guanine is $75$ and those of thymine is $75$. The total number of nucleotides in the segment will be:
