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.

a codon that does not specify an amino acid, and serves much as a comma or a period punctuating the genetic message

That codon at which translation of an mRNA molecule into a polypeptide is terminated. In the Universal Code this may be: UGA, UAG, or UAA.

The three codons, UAA , UAG and UGA , that do not code for an amino acid but act as signals for the termination of protein synthesis.

One of the three codons that marks the position where translation of an mRNA should stop.

One of three codons (UGA, UAG, UAA) that code for termination of transcription of a mRNA and release of the newly synthesized polypeptide chain.

The codon on a messenger RNA molecule where protein synthesis stops.

The codons UAA, UGA, or UAG, which cause the termination of translation.

A three-base-pair sequence in DNA that does not code for an amino acid, and thus results in termination of the protein sequence.
