A stop codon signals the end of an amino acid chains A STOP codon marks the end of a segment of DNA that is to be transcribed. During transcription, a molecule of messenger RNA (mRNA) is synthesized. The base sequence of this RNA is determined by the base sequence of the template strand of the DNA being transcribed.
When the transcription process reaches a STOP codon, that codon is the last to be transcribed. The mRNA therefore ends with a STOP codon. By convention, the gene is considered to be the base sequence on the non-template strand of DNA, and there are three STOP codons: TAA, TGA, TAG. Any one of these marks the end of the gene.
The corresponding STOP codons in mRNA are: UAA, UGA, UAG.
Mitochondria contain DNA, with 37 genes. In animals, mitochondrial DNA uses TGA (UGA in the mRNA) to code for one of the amino acids, tryptophan, and not as a STOP codon. Plant mitochondria use the "standard" code, with three STOP codons.
A a stop codon does NOT code for an Amino Acid.
In fact it transcribes nothing, so following amino acids have nothing to attach on to, and the polypeptide chain will end.

It SYNTHESIZES proteins, but CODES for amino acids
for translation of RNA into protein to end
Amino Acids
Each codon codes for a specific amino acid.
an anti-codon is a code for an amino acid found on protein
It is CAC and CAU.
One codon specifies a specific amino acid. However, more than one codon can code for the same amino acid. For example, the codon GUU codes for the specific amino acid valine; and the codons GUC, GUA, and GUG also code for valine.
The amino acid that is encoded by the initiation codon AUG is methionine. It is the only amino acid which is specified by just one codon.
A codon is a unit of genetic code
Each codon codes for a specific amino acid.
The codon could code for a different animo acids.
an anti-codon is a code for an amino acid found on protein
The open A side attaches to the codon. The codon is three nucleotides that stick together and form a genetic code in a DNA.
A codon
AUG
It is CAC and CAU.
The three coding letters on mRNA are known as a codon. They code for a specific amino acid to be added to the protein chain being created.
Codon Tables have to do with DNA sequencing. You cannot purchase them online. You can view samples of Codon Tables on the Wikipedia. Once on the website, search for Genetic Code.
One codon specifies a specific amino acid. However, more than one codon can code for the same amino acid. For example, the codon GUU codes for the specific amino acid valine; and the codons GUC, GUA, and GUG also code for valine.
I don't understand your question. mRNA does not have triplets. Did you mean codon? Triplet refers to DNA, codon to mRNA.
