In an analysis of the nucleotide composition of double-stranded DNA to see which bases are equivalent in concentration,which of the following would be true?
A) A = C
B) A = G and C = T
C) A + C = G + T
D) A + T = G + C
E) A = G and C = T and A + C = G + T are both true.

In double-stranded DNA, the amount of adenine (A) equals thymine (T), and the amount of cytosine (C) equals guanine (G). Therefore, the sum of purines (A + G) equals the sum of pyrimidines (C + T), leading to A + C = G + T.
