|
|
the base-pairing rules
|
|
|
the fact that the DNA molecules are enclosed within a DNA nucleotide
|
Explanation:
Detailed explanation-1: -So the DNA replication is possible only by the complementary base pairing of the nucleotides Adenine with thymine and guanine with cytosine. These nucleotides are bound to each other with the help of hydrogen bonds and the phosphate backbone is meant to provide support to the DNA molecule.
Detailed explanation-2: -Replication relies on complementary base pairing, that is the principle explained by Chargaff’s rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
Detailed explanation-3: -What makes exact DNA replication possible? The geometry of individual base pairs allows only one base to form a hydrogen bond with its complement base.
