Is DNA Multilingual?
The genetic code is the biochemical basis of life, and given its central importance, there are rules. Double-stranded DNA is transcribed to single-stranded RNA, which is processed through protein-building ribosomes. Each set of three nucleotide bases (a codon) corresponds to a particular amino acid; when a given triptych is being read, the appropriate amino acid swoops in and is added to a growing chain. A protein is born.
