Question

In a DNA percentage of thymine is 20% then what will be percentage of guanine?
(1) 20%
(2) 40%
(3) 30%
(4) 60%

Answer 1

30 percent

thymine is 20 % so as the adinine is also 20% , beacuse adinine always pair with thymine therefore the percentage of adinine and thymine is 20+20 = 40% , thus the remaining 60%is of guanine and cytosine ., if cytosine is 30% then the percentage of guanine is also 30%
