Keywords:  codon, uag, uaa, uga, mrna
A UAG, UAA. or UGA codons which is not representing any cognate aminoacyl tRNA in most organisms. When the ribosome encounters a stop codon in the mRNA, a termination factor interacts with the ribosome causing polypeptide synthesis to stop and the ribosome to dissociate from the mRNA.
A codon on mRNA that signals the termination of DNA translation. There are three stop codons: UAA, UAG, or UGA.
a termination codon. It is made up of three bases and is located in a strand of DNA. Its presence signals that translation should stop at that point.
