Quizplus · Accepted Answer

The fraction of cytosine and thymine in a DNA molecule varies depending on the specific DNA sequence. DNA sequences are highly variable, and the proportion of each nucleotide (adenine, thymine, cytosine, guanine) can differ widely among different organisms and even within different regions of the genome of a single organism.
