It is a universal code and serves all organisms in nature. The reading of the DNA genetic code is read every three nucleic acids (a nucleic acid corresponds to a letter totaling 64 possible combinations, as each triple of nucleic acids can have four amino acid bases; this means that a strand of DNA is transformed on an RNA strand).
Other
