Describe your reasoning. As guanine and cytosine are complementary, another 15% of the nucleotides must have cytosine. The remaining 70% of the nucleotides (100%-30%) must have adenine and thymine in equal proportions (35% each), as they are complementary to each other.f 15% of the nucleotides in a DNA molecule contain guanine, what percentage of the nucleotides having each of the other three bases?
Rating Newest Oldest. Best Answer: 15% would be cytosine because it base pairs with guanine so their percentage would be equal the remaining 70% would be split between thymine and adenin. Because these base pair they will have a 1:1 ratio meaning the 70% will be divided in two so, 35% thymine, 35% adenine.Source(s): just now. Report Abuse. Remember, guanine binds to cytosine and adenine binds to thymine. Therefore, if 15% of DNA is guanine, 15% of DNA has to be cytosine. The rest of the DNA (100-30=70) must be thymine and adenine. 70/2 = 35% for thymine and adenine.
