If 15% of the nucleotides in a DNA molecule contain guanine, what percentage of the nucleotides contain each of the other three bases?
-
nucleotides that compose DNA bind together in complementary base pairing. Meaning that in DNA Guanine will always bind to Cystosine, and Adenine will always bind to Thymine.
Since you know that 15% of the DNA is Guanine then it must also contain 15% Cytosine.
So far you have 30% of the nucleotides accounted for, which mean the remaining 70% is equally split between Adenine and Thymine at 35% each.
Note- for RNA molecules Thymine is replaced with Uracil
