Definition: Genetic expression is a process that takes inherited information in your genes (like your DNA sequence), and from that information makes a specific functional product (sometimes called a gene product) such as RNA (ribonucleic acid) or protein.
Also Known As: gene expression
Examples:
Normal breast tissue cells have a particular genetic expression, which changes when they turn into cancer. Some gene expression tests can reveal how breast cancer cells are different from normal cells and the results might lead to more accurate diagnosis and treatment.
