Question

If a segment of dna has 20% adenine in its base composition, what percent thymine is there?

Answer 1

20%

Step-by-step explanation:

Since adenine's complementary base pair is thymine, they'll have an equal percent. 20+20=40, so if you get another question about how much guanine or cytosine, it'll be 30 because 30+30=60 and 40+60=100. Hope this helps :)
