Gene Mutation - English Definition & Meaning

Definition

A "gene mutation" is a change in the DNA sequence that makes up a gene. This change can alter the protein that the gene codes for, or prevent the gene from functioning properly. Think of it as a typo in the instruction manual for building a specific protein in your body. Mutations can range from small changes affecting a single DNA base to larger alterations affecting entire genes. These mutations can be inherited or arise spontaneously. The consequences can vary from no effect to serious diseases. A gene mutation fundamentally alters the instructions for a particular protein.

Etymology

"Gene" comes from the Greek word "genos," meaning birth or origin. "Mutation" comes from the Latin word "mutare," meaning to change. A "gene mutation" refers to a change in the origin or fundamental unit of heredity. The term arose with the development of genetics and the understanding of how genes control traits. It's central to understanding inherited diseases and evolution.
