18%.
If a cell contains 32% cytosine then it contains the same amount of its base pair, guanine. That means 64% of the cell is cytosine and guanine. The remaining 32% must be adenine and thymine, of which there should be equal amounts. Therefore to fine the amount of thymine divide 32 in half, which gives you 18%.

Answer:

is it 18%?

Explanation:

I don't think this is correct, but the four bases are adenine, thymine, guanine, and cytosine. So, if there is 32% cytosine then there has to be 32% guanine because that pairs up with cytosine. so percentages are out of 100, meaning that 100-64=36 which is how much percent we have left for the other two bases. 36/2=18 which would be the percent of adenine and thymine because those two pair up in dna.
