The DNA recipes for proteins are in the links between the two spirals.

Each link is made of two __bases__. The bases are labeled A, C, G and T.

A base and its part of the spiral is called a __nucleotide__.

Bases form __base pairs__, A-T, C-G, G-C and T-A. These are the "rungs" of the "ladder".

A string of bases that makes a protein is called a protein-coding __gene__.
