What are the base-pairing rules in DNA?
|
A-C, G-T
|
|
A-U, G-C
|
|
A-T, G-C
|
|
A-C, G-U
|
Explanation:
Detailed explanation-1: -The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)
Detailed explanation-2: -The type of bonds between A-T and G-C base pairs are hydrogen bonds. There are two hydrogen bonds between A-T base pairs, while there are three hydrogen bonds between the G-C base pair. These hydrogen bonds between the complementary bases help hold the two DNA strands together.
