The genetic code is a nearly universal language that encodes directions for cells. The language uses DNA nucleotides, arranged in codons of three, to store the blueprints for amino acid chains.
Universal Genetic Code and its Natural Variations. Abstract. The universal genetic code is a common language for almost all organisms to translate nucleotide sequences of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) to amino acid sequences of proteins. However, the genetic code is still evolved. Nonuniversal genetic codes are found in some organisms and organelles. Aminoacylâtransfer RNA (tRNA) synthetases and RNA modifications play a critical role in reassignment of the genetic code.
