In an analysis of the nucleotide composition of a double stranded DNA to see which
bases are equivalent in concentration, which of the following would be true?
A = G and C = T and A + C = G + T are both true.
A = G and C = T
A + T = G + C
A + C = G + T
A = C
The correct answer is A+C=G+T but I would like a detailed explanation as to why, thank you.
