In DNA, purines and pyrimidines bind with each other to form what are known as base pairs. If you imagine ... are broken down into groups of three nucleotide bases, known as codons.

One goal of the project was to accurately sequence the 3 billion nucleotide base pairs in the human genome. A second goal was to map and identify all of the human genes present in the DNA sequence.

also called base pairs. Two types of base pairing occur: nucleotide A pairs with T, and nucleotide C pairs with G.

A sugar molecule, a base, and a phosphate molecule group together to make up a nucleotide ... Cytosine (C) will "pair" to guanine (G), and adenine (A) will "pair" to thymine (T).

DNA consists of four chemical units, called nucleotide bases: adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair up with each other (A with T and C with G) to form units called ...

The highly specific nucleotide interaction following the Watson-Crick base pairing rule, as well as the chemically tunable groups present in DNA, makes it possible to encode both structural and ...
