If the Quantities of the Four Bases in a DNA

Question

If the quantities of the four bases in a DNA molecule are measured, we find that
A) A = C and G = T.
B) T = A and C = G.
C) A = G and C = T.
D) no two bases are equal in amount.
E) all bases are equal in amount.

Accepted Answer

This is because in DNA, adenine (A) forms a base pair with thymine (T) and cytosine (C) forms a base pair with guanine (G). Therefore, the amount of A in a DNA molecule must be equal to the amount of T, and the amount of C must be equal to the amount of G.
