The UAG codon is a special kind of codon called a stop codon. There are three types of stop codons: amber, ochre, and opal. UAG is an mRNA codon that is specific for the amber stop codon. The amber codon was named after Harris Bernstein, then a Caltech graduate student, whose last name means "amber" in German.

What is the function to stop a codon?
the stop codon uaa, uag, or uga triggers the ending of the transcription process
What protein sequence is coded by the code UAG?
The sequence UAG is the mRNA codon that means "stop" and does not code for an amino acid.
What code tells a cell to stop making a protein?
A codon at the end of RNA signals the end of transcription. This is encoded by the codon sequence UAA, UGA, or UAG.
Which mRNA codons will start the process of translation?
If you're referring to stop codons, then there are three: UAA, UAG and UGA. They do indeed stop translation, though I wouldn't say they halt ribosomes. Stop codons code for a releaser enzyme, one that fits the A site of the ribosome, but does not carry an amino acid. This enzyme cuts the bond between the polypeptide and the last tRNA.
How does the termination of translation occur?
The termination of protein translation is caused by termination codon. Termination happens when a stop codon is reached, there is no amino acid to be incorporated and the entire assembly releases the newly synthesized polypeptide.
What amino acid is UAG?
UAG in RNA is amber. In RNA it is a stop codon which is a nucleotide triplet within messenger RNA that signals a termination of translation.
What is the function to stop a codon?
the stop codon uaa, uag, or uga triggers the ending of the transcription process
What protein sequence is coded by the code UAG?
The sequence UAG is the mRNA codon that means "stop" and does not code for an amino acid.
Do stop codon have an amino acid?
A stop codon (UGA, UAA, UAG) only codes for a stop. No amino acid results from a stop codon.
What codon starts polypeptide synthesis?
The codons are UAA,UAG and UGA
What do you mean by stop codons?
a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation.Three codons UAG,UAA & UGA are the stop codons, which denotes the end of the protien.
What codons stop protein synthesis?
UAA, UAG, and UGA are stop codons.Sequence UAA, UAG, and UGA are the three stop codons. There is only one start codon, AUG.
What code tells a cell to stop making a protein?
A codon at the end of RNA signals the end of transcription. This is encoded by the codon sequence UAA, UGA, or UAG.

If you're referring to stop codons, then there are three: UAA, UAG and UGA. They do indeed stop translation, though I wouldn't say they halt ribosomes. Stop codons code for a releaser enzyme, one that fits the A site of the ribosome, but does not carry an amino acid. This enzyme cuts the bond between the polypeptide and the last tRNA.
What what and what are stop codons?
The start codon on a messenger RNA strand marks the start point of translation from RNA to protein. It is nearly invariably AUG (which translates to the amino acid methionine). Tip for remembering: "Are you good?" The stop codon on the other hand marks the end point of translation. It can be UAG, UAA or UGA. Tip for remembering: "You are good"/"You are awful"/"You are good and awful"
How does the termination of translation occur?
The termination of protein translation is caused by termination codon. Termination happens when a stop codon is reached, there is no amino acid to be incorporated and the entire assembly releases the newly synthesized polypeptide.
When does translation end?
Translation ends when a stop codon is reached. The stop codons are: * UAA * UAG * UGA
