Explanation:
Detailed explanation-1: -A+T = 100-40 =60, Adenine percent= 60/2= 30.
Detailed explanation-2: -Thus, If a double stranded DNA has 20% of cytosine, it has 20% of guanine. Thus, cytosine plus guanine make 40% of the total bases. The remaining 60% includes both adenine and thymine which are in equal amounts.
Detailed explanation-3: -It means that the number of adenine molecules is equal to thymine molecules and the number of guanine molecules is equal to cytosine molecules. <br> %A = %T and % G = % C <br> If dsDNA has 20% of cytosine, then according to the law, it would have 20% of guanine.
Detailed explanation-4: -Answer: There would be 20% Cytosine.
