Vedclass · Answer

(B) According to Chargaff's rule,the total amount of purines equals the total amount of pyrimidines,and the sum of all four bases is $100\%$.Given that the sum of cytosine $(C)$ and guanine $(G)$ is $40\%$,we have $C + G = 40\%$.Since the total percentage of all bases $(A + T + C + G)$ is $100\%$,we can write $A + T + 40\% = 100\%$.Therefore,$A + T = 100\% - 40\% = 60\%$.According to the base pairing rules,the amount of adenine $(A)$ is equal to the amount of thymine $(T)$.Thus,$2A = 60\%$,which means $A = 30\%$.Therefore,the content of adenine is $30\%$.

If the content of cytosine and guanine in $DNA$ is $40\%$,what is the content of adenine (in $\%$)?
