And then they become mutations, which may eventually lead to cancer. This is especially true if the mutation occurs in a tumor suppressor gene or oncogene. Mutations in DNA repair genes can be inherited, such as with Lynch syndrome, or acquired. Despite all that is known about the different ways cancer genes work, many cancers cannot be linked to a specific gene.
Abstract. A nonsense mutation occurs when a sense codon, one that codes for an amino acid, is changed to one of the chainâtermination codons, UAG, UAA or UGA. A nonsense suppressor can result from a second mutation affecting the translational apparatus. This mutation enables the cell to insert an amino acid in response to the nonsense codon, resulting in a wildâtype or near wildâtype phenotype. Some suppressor mutations change the anticodon of a transfer ribonucleic acid (tRNA) such that it can pair with the nonsense codon.
