WebThe result is a sandy-colored mouse. The mutated version of the Mclr gene, however, triggers melanocytes to increase the production of eumelanin, resulting in the dark coat-color phenotype. GENE MUTATION A gene mutation is any change in the DNA sequence of a gene. Gene mutations can change the structure of the resulting protein. WebSo if there is a mutation that changes an AAG to an AAA, the cell will still put in a Lys. This is a silent mutation. Sounds simple enough—basically adding amino acids one after the other until a protein is made. Which explains why silent mutations are usually pretty harmless. They don’t change the amino acid that gets put in. can shaolin monks fight https://mintpinkpenguin.com

However, this study raises the possibility that even ‘silent’ mutations could contribute to the development of cancer and many other ... WebA silent mutation is caused by a base substitution that does not change the amino acid sequence, and therefore will not affect the phenotype. For example, substituting the A with G still results cysteine. b. More than one codon can code for the same amino acid. For example, six different codons code for leucine.
