Answer:
Thymine = 36%
Explanation:
Since cytosine and guanine are found in similar quantities, their sum can clearly be divided by 2.
As there are only four bases in DNA, you know, all four bases combined must be equal to 100% of the sample. Provided the knowledge that the sample is 20 percent guanine, because guanine and cytosine pair with each other, you might presume it is also 20 percent cytosine. That is, together, 40 percent of the overall sample
