The genetic code is the set of rules by which information encoded in genetic material (DNA or RNA sequences) is translated into proteins (amino acid sequences) by living cells. A more precise term f...

The same codons are assigned to the same amino acids and to the same START and STOP signals in the vast majority of genes in animals, plants, and microorganisms. However, some exceptions have been found. Most of these involve assigning one or two of the three STOP codons to an amino acid instead.

Here we show that a statistical excess of stop codons has evolved at the third codon downstream of the real stop codon UAA in yeasts. Comparative analysis indicates that stop codons at this location are considerably more conserved than sense codons, suggesting that these tandem stop codons are maintained by selection.

A stop codon tells the cell's machinery that it has reached the end of the protein and should stop translating the code. Stop codons come in three different forms - TGA, TAG, and TAA. Find stop codon; Location: chromosome 1: bases 215847819-215860406 (reverse complemented) located in 1q31.1;

Stop codons: the Good, the Bad, and the Ugly ... Stop codons are a normal part of protein synthesis--they're the reason that all proteins don't go on 'forever'. Given a translation machinery that simply puts one foot in front of the other endlessly, a mechanism must exist for derailing the machine when its work is done.
