Frameshift coding

WebHow does a frameshift mutation in the gene coding for the enzyme, hexosaminidase A, result in Tay-Sachs disease? The mutation results in incorrect synthesis of the enzyme. The mutation... Webthere is a chance that point mutations might code for the same amino acid, but a frameshift mutation completely alters the reading frame coding for entirety different amino acids. Therefore, frameshift mutations are likely to cause more problems than point mutation. A NONSENSE MUTATION occurs when a codon is changed to a STOP codon. Many ...

Web(2) MSm and MSf are the mismatch and frameshift MS of a genetic code, respectively. As -1 and +1 frameshift MS are identical, only +1 frameshift MS is considered. (3) For each AA property: Pm/Pf is the probability of mismatch/frameshift optimality of the SGC; Pm/Pf is given by the fraction of codes with MSm/MSf values lower than that of the SGC.
