Question

In a DNA sample, 15% of the bases are thymine (T). What percentage of the bases in this sample are cytosine (C)?

A. 15%

B. 30%

C. 35%

D. 85%

Answer 1

C) 35%

Step-by-step explanation:

Thymine pairs with adenine. If thymine is 15% then so would adenine be 15%. That leaves the reaminder to be 70%. Cytosine pairs with guanine, thereby, they would each be 35%.
