The four bases are arranged in groups of three in a specific order, each group acting as a unit (codon), which specifies a particular amino acidSee also messenger RNA, transfer RNA Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co.

A simple mnemonic is “One gene codes for one protein which runs one reaction.” notes for genetic codeAll living things share the same genetic code, a fact that represents strong evidence for evolution. Unraveling the genetic code was one of the great scientific achievements of the twentieth century, and it opened the way to genetic engineering.

Scientific definitions for genetic codegenetic code [ jə-nĕt′ĭk ] The sequence of nucleotides in DNA and RNA that serve as instructions for synthesizing proteins. The genetic code is based on an alphabet consisting of sixty-four triplets of nucleotides called codons. The order in which codons are strung together determines the order in which the amino acids for which they code are arranged in a protein. The American Heritage® Science Dictionary Copyright © 2011.
