Nucleotide pairing refers to the specific base pairing interactions between the nucleotides of DNA or RNA molecules. In DNA, adenine pairs with thymine, and cytosine pairs with guanine through hydrogen bonding. In RNA, uracil replaces thymine in pairing with adenine. These base pair interactions are essential for maintaining the structural integrity and information coding in nucleic acid molecules.

A unique mono-nucleotide of RNA is uracil (U), which pairs with adenine (A) in RNA molecules. Uracil is not found in DNA, where thymine (T) replaces it in base-pairing with adenine.
In DNA, the nucleotide matches are adenine (A) pairing with thymine (T), and cytosine (C) pairing with guanine (G). In RNA, adenine (A) pairs with uracil (U) instead of thymine (T).
Nucleotide pairing affects the action of DNA polymerase.
The nucleotide bases of DNA are located at the center of the twisted ladder or double helix structure. They are paired up across the helix, with adenine pairing with thymine and guanine pairing with cytosine through hydrogen bonds.

The sequence of nucleotides in the template DNA strand determines which complementary nucleotide will be added to the growing strand. A-T and G-C base pairing rules govern the selection of the nucleotide to be added during DNA replication.
Base pairing rules
A unique mono-nucleotide of RNA is uracil (U), which pairs with adenine (A) in RNA molecules. Uracil is not found in DNA, where thymine (T) replaces it in base-pairing with adenine.
In a double chain of DNA, the nucleotide adenine (A) pairs with thymine (T) via complementary base pairing.
In DNA, the nucleotide matches are adenine (A) pairing with thymine (T), and cytosine (C) pairing with guanine (G). In RNA, adenine (A) pairs with uracil (U) instead of thymine (T).
Nucleotide pairing affects the action of DNA polymerase.
The nucleotide bases of DNA are located at the center of the twisted ladder or double helix structure. They are paired up across the helix, with adenine pairing with thymine and guanine pairing with cytosine through hydrogen bonds.
The base cytosine pairs with guanine via three hydrogen bonds. They are complementary base pairs in the DNA double helix.
Adenine can only bond to thyamine and cynanine can only bond to guamine (A to T, C to G).
The most stable DNA nucleotide pair is thymine (T) paired with adenine (A) due to forming two hydrogen bonds. This pairing is more stable than cytosine (C) with guanine (G), which forms three hydrogen bonds.
RNA polymerase blinds to the first DNA nucleotide and begins pairing complementary base and continues down the DNA until reached a point called the Termination Single
