In an Analysis of the Nucleotide Composition of DNA,which of the Following

Question

In an analysis of the nucleotide composition of DNA,which of the following will be found?
A)A = C
B)A = G and C = T
C)A + C = G + T
D)G + C = T + A

Accepted Answer

In DNA, the number of adenine (A) nucleotides is always equal to the number of thymine (T) nucleotides, and the number of cytosine (C) nucleotides is always equal to the number of guanine (G) nucleotides. This means that A + C = G + T, which is the only choice that reflects this parity in nucleotide composition. A = C (Option A) and A = G and C = T (Option B) are incorrect because they do not reflect the equal amounts of all four nucleotides present in DNA. G + C = T + A (Option D) is also incorrect because it incorrectly suggests that guanine (G) and cytosine (C) always pair with thymine (T) and adenine (A), respectively, which is not true.
