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. WebSilent mutations create problems with exonic splicing enhancers (ESEs), resulting in changes in mRNA processing of the genetic information.
