According to Chargaff's rule, base pairing in DNA should resemble which of the following?

A. [tex]A = T \; ; \; C = G[/tex]
B. [tex]A = C \; ; \; T = G[/tex]
C. [tex]A = G \; ; \; T = U[/tex]
D. [tex]A = U \; ; \; C = G[/tex]


Sagot :

According to Chargaff's rule, the amounts of adenine (A) and thymine (T) in DNA should be approximately equal, and the amounts of cytosine (C) and guanine (G) should also be approximately equal. This rule reflects the base pairing in DNA, where adenine pairs with thymine and cytosine pairs with guanine.

Thus, the correct representation of base pairing in DNA, as per Chargaff's rule, is:

[tex]\[ A = T ; C = G \][/tex]

So, the correct answer is:

[tex]\[ A = T ; C = G \][/tex]
