A sample of double-stranded DNA contains 28% thymine. Approximately what percent of the nucleotides in this sample will be guanine

If DNA contains 28% Thymine, then approximately 22% of the nucleotides in this sample will be Guanine.

DNA is a double helix molecule composed of two chains of nucleotides linked together by hydrogen bonds.In DNA, there are four classes of nucleotides that contain different nitrogenous bases: Thymine, Guanine, Adenine, Thymine.According to the base pair rules, Adenine pairs with Thymine and Guanine pairs with Cytosine.Thus, the percentage of Thymine must be equal to Adenine (28%), while the remaining percentage is equal to the sum of Guanine + Cytosine (28 + 28 = 56 >> 100 -56 = 44).In consequence, the percentage of Guanine, in this case, is equal to 22% (22 G + 22 C = 44).

In conclusion, if DNA contains 28% Thymine, then approximately 22% of the nucleotides in this sample will be Guanine.
