Genetic code. The genetic code is the set of rules by which information encoded in genetic material (DNA or RNA sequences) is translated into proteins (amino acid sequences) by living cells. Specifically, the code defines a mapping between tri-nucleotide sequences called codons and amino acids; every triplet of nucleotides in a nucleic acid sequence specifies a single amino acid.
However, it took some time before they figured out how the base pairs accomplished this coding. Scientists main problem lay in the fact that while there were only 4 nitrogen bases (nucleotides), there were 20 amino acids for which those nucleotides had to code. If adenine, thymine, guanine, and cytosine each coded for a particular amino acid, then the DNA/mRNA information system would only be able to code for 4 amino acids.
