Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA, can you use it to predict the amounts of all four nucleotide bases when you only know the amount of one type of base? Approximately 21% of the human genome is comprised of nucleotides containing C. Given this information, calculate the percentage of the human genome that is comprised of nucleotides containing G, T, and A.

G=21 %

T = 29 %

A = 29 %

Explanation:

Since C only binds to G, you have the same amount of C and G, so G is 21 %.

100 % minus 42 % (21 % C plus 21 % G=) equals 58 %.

So the other 58 % is made of T and A. Since T only binds to A, the half of the extra 58 % is T and the other half is A. Therefore 29 % is T and 29 % is A
