Question

If 15% of a DNA double helix is the base adenine what are the percentages for the following bases?

Thymine _____
Guanine _____
Cytosine _____

Answer 1

Thymine 15%

Guanine 30%

Cytosine 30%

Step-by-step explanation:

Remember Chargaff's rules: C=G, T=A.

A = T

.15 = T

Now we've got .30 A and T, so we know 1 - .3 = .7 of the DNA should be guanine and cytosine.

.7 / 2 = .35

.35 = G

.35 = C
