"Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA
Dima020 [189]

Answer:

G - 21%

T - 29%

A - 29%

Explanation:

Nucleotide bases in DNA are complementary. Adenosine (A) binds to Thymine (T) while Cytosine (C) binds to Guanine (G). Hence the composition of A in DNA is the same as that of T; and that of C is the same as that of G.

From the information given, C is 21%

Therefore G is also 21% of the genome as  C is bound to G, the therefore are the same proportion.

C and G make up 42% of the genome (that 21% + 21%).

The remaining 58% (100%-42%) is made up of A + T

Similarly the proportion of A is equal to that of T,

Hence A is 29% (half of 58%) and T is 29%.
