biochemist erwin chargaff found that in dna there was a special relationship between individual bases that we now refer to as
chargaffs rule. his observation was that the number of
______ was equal to the number of adenines (a), and the number of
______ was equal to the number of guanines (g).
o i, a
o g, a
o g, c
o c, t
o i, c

Explanation:

Chargaff's rule states that in DNA, the number of adenines (A) is equal to the number of thymines (T), and the number of guanines (G) is equal to the number of cytosines (C). This is due to the base - pairing rules in DNA (A - T and G - C).

Answer:

A. T, C. T
