Triplet

 

transcribed from the DNA molecules from the mRNA molecules in the cytoplasm as a template for protein synthesis ,Nike Free 6.0 Mens, mRNA molecule coding region of the nucleotide sequence as the genetic code (Genetic code), the protein Synthesis process of being translated into the amino acid sequence of the protein . MRNA molecules in organisms to a nucleotide sequence mode of translation with three adjacent nucleotides units ,Nike5 Boots, such as AUG methionine and is recognized as a start signal peptide bond synthesis , UCU allowed into nascent chain serine , UGA will is recognized as a termination signal . Arranged in series so that the three nucleotides are referred to as a triplet codon (coden). Four kinds of nucleotides constituting the mRNA can form combinations by codons 64 , 61 directly in the 20 kinds of coded amino acids used in protein synthesis ; another three does not encode any amino acid , and as a synthetic peptide chain termination codon Son (terminator codon).
