Genetics Code
The genetic code is the set of rules by which
information encoded within DNA or mRNA
sequences is translated into proteins by living cells.
Each codon consists of three nucleotides, usually
representing a single amino acid. The nucleotides are
abbreviated with the letters A, U, G and C. This is mRNA,
which uses U (uracil). DNA uses T (thymine) instead. This
mRNA molecule will instruct a ribosome to synthesize a
protein according to this code.
