Answer:
17%
Step-by-step explanation:
Adenosine is not complementary to cytosine, so their percents won't be equal. You'd need to find out the percents of the purines(Adenosine and Thymine) that are there. You'd add 33 and 33 to make 66. 100-66=34. 34% is the pyrimidines in the dna. you'd divide it by two to find how much cytosine there is—leaving you with 17%.
