Which Relationship About Nucleotide Composition in DNA is Correct

Question

Which relationship about nucleotide composition in DNA is correct?
A)C+G=A+T
B)C+A=G+T
C)C=A
D)G=T
E)C=T

Accepted Answer

B) C+A=G+T is correct because in DNA, the amount of cytosine (C) plus adenine (A) equals the amount of guanine (G) plus thymine (T), reflecting the base pairing rules where A pairs with T and C pairs with G.
