answered by Lifeeasy Authors. 1  The ribosome moves forward on the m-RNA, one codon at a time and finally reaches the termination codon (UAA/ UAG/ UGA). 2  As termination codon does not code for any amino acid, the polypeptide chain breaks and the protein molecule is seperated.
There are three stop codons: UAG, UAA, and UGA. In DNA, the uracil (U) is replaced by thymine (T). If a change in the DNA sequence, or mutation, of a gene occurs that creates a stop codon, this is called a nonsense mutation.A nonstop mutation is a change in the sequence of a stop codon that turns it into a codon that specifies an amino acid. To unlock this lesson you must be a Study.com Member.onsense mutations occur when a codon that is supposed to specify an amino acid is changed to a stop codon instead. This results in a protein that is shorter than normal because it cannot finish adding all the necessary amino acids. These truncated proteins are often not functional.
