Definition: Gene expression is the process by which information in a gene is transcribed and translated to produce a functional product (RNA or protein) that affects a cell’s structure or function.

Examples:
1) Pancreatic beta cells express the insulin gene to produce insulin and regulate blood glucose.
2) Erythroid precursor cells express globin genes to synthesize hemoglobin for oxygen transport.

Sentence using it: Researchers tracked changes in gene expression to see how stem cells differentiate into nerve cells.
