Question

in analyzing the number of different bases in a dna molecule, which result would be consistent with chargaffs rules?
a + g = c + t
a = g
a = c
g = t
a + t = g + c

Explanation:

Chargaff's rules state that in DNA, the amount of adenine (A) equals the amount of thymine (T), and the amount of guanine (G) equals the amount of cytosine (C). So, the sum of purines (A + G) equals the sum of pyrimidines (C + T).

Answer:

A. A + G = C + T
