Question:
If the base adenine constitutes 31% of an isolated DNA fragment, then write what will be the expected percentage of the base cytosine in it. Explain how did you arrive at the answer given.
If the base adenine constitutes 31% of an isolated DNA fragment, then write what will be the expected percentage of the base cytosine in it. Explain how did you arrive at the answer given.
Show Hint
The Chargaff’s rule states that in DNA, the percentage of \(A = T\) and \(C = G\), with the total equalling 100\%.

Solution and Explanation
Adenine (\(A\)) pairs with Thymine (\(T\)), so \(A + T = 31\% + 31\% = 62\%\).
Cytosine (\(C\)) pairs with Guanine (\(G\)), and since \(C + G = 100\% - (A + T) = 38\%\), the percentage of cytosine is \(C = 19\%\).
