The tool calculates the optimal degenerate codons encoding the amino acids from the user input.
If you want to know the amino acids encoded by specified degenerate codon, please visit Calculate the amino acids encoded by degenerate codon
Input amino acids types:
Degenerate Condon
Proteins are translational products of the genetic information encoded in nucleotide sequences of RNA and/or DNA. The genetic code specifying each amino acid consists of three nucleotide units called codons. Among the possible 64 codons arising from the combination of four natural nucleotides, 61 codons specify amino acids, and the remaining 3 codons code for translation “stop”. Since there are only 20 natural amino acids used as building blocks for proteins, many amino acids are specified by more than one codon, a phenomenon known as codon degeneracy.
