If an organism contains 13% adenine in its DNA,its GC content is _____.
A)13%
B)26%
C)74%
D)37%

Question

Quizplus · Accepted Answer

In a DNA molecule, the amount of adenine (A) is equal to the amount of thymine (T), and the amount of guanine (G) is equal to the amount of cytosine (C). Given that adenine is 13%, thymine will also be 13%, making A+T = 26%. Since the total DNA content must equal 100%, the remaining percentage is for G+C, which is 100% - 26% = 74%.
