The gamma function is implemented in the Wolfram Language as Gamma[z]. There are a number of notational conventions in common use for indication of a power of a gamma functions. While authors such as Watson (1939) use (i.e., using a trigonometric function-like convention), it is also common to write .
A codon specifies a certain amino acid that makes up the protein. A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop sigâ¦nal during protein synthesis.    Codon is a genetic code. The genetic code is initial nucleotide  from which translation starts.
Stop codon. In the genetic code, a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation. Proteins are based on polypeptides, which are unique sequences of amino acids. Most codons in messenger RNA (from DNA) correspond to the addition of an amino acid to a growing polypeptide chain, which may ultimately become a protein. Stop codons signal the termination of this process by binding release factors, which cause the ribosomal subunits to disassociate, releasing the amino acid chain. While start codons need nearby sequences or initiation factors to start translation, a stop codon alone is sufficient to initiate termination.
