Vedclass · Answer

(C) According to Chargaff's rule,the amount of adenine $(A)$ is equal to the amount of thymine $(T)$,and the amount of guanine $(G)$ is equal to the amount of cytosine $(C)$.Given that the percentage of adenine $(A)$ = $30\%$.Therefore,the percentage of thymine $(T)$ = $30\%$.The total percentage of $A + T = 30\% + 30\% = 60\%$.The remaining percentage for $G + C$ is $100\% - 60\% = 40\%$.Since $G = C$,the percentage of guanine $(G)$ = $40\% / 2 = 20\%$.Thus,the correct option is $C$.

In the $DNA$ of an animal,the percentage of adenine is $30$. What would be the percentage of guanine?
