Question

According to Chargaff's rule of base pairing, which of the following is true about DNA?

A. ANG and C = T
B. A = T and C = G
C. A = T = G = C
D. AC and GET

Answer 1

According to Chargaff's rule of base pairing, DNA follows complementary base pairing, where A always pairs with T and C always pairs with G.

Step-by-step explanation:

According to Chargaff's rule of base pairing, the correct statement about DNA is B. A = T and C = G.

In DNA, adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G). This is known as complementary base pairing. The base pairs are stabilized by hydrogen bonds, with A and T forming two hydrogen bonds, and C and G forming three hydrogen bonds.
