The sugar molecules thus formed contain carbon, hydrogen, and oxygen: Their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins or DNA), used for example to form new cells.

There are 4 nucleotides. Guanine (G), Cytosine (C), Thymine (G) and Adenine (A).
C and T are called pyrimidines, and are longer than G and A.
G and C connect using 3 hydrogen bonds, but A and T bond using only 2.
