chargaffs rules of dna structure states that
a) a + t = g + c.
b) a = t, c = g
c) a = c, t = g.
d) a = g, t = c.
e) the number of purines in dna never equals the number of pyrimidines.

Explanation:

Chargaff's rules state that in DNA, the amount of adenine (A) is equal to thymine (T), and the amount of cytosine (C) is equal to guanine (G). This is due to the base - pairing rules in DNA (A - T and C - G).

Answer:

B. A = T, C = G
