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. WebMar 5, 2024 · The majority of mutations have neither negative nor positive effects on the organism in which they occur.
