What is the Meaning of Gene Expression?

Gene expression is the fundamental process by which information encoded in a gene's DNA sequence is converted into a functional product, such as a protein or a non-coding RNA molecule. This process is the molecular basis for all cellular structure and function, determining the specific characteristics and activities of a cell or tissue. Hormones and environmental factors serve as potent regulators, directly influencing which genes are turned "on" or "off" at any given time. Understanding this process is key to personalized medicine.

What is the Origin of Gene Expression?

The term is a direct combination of "gene," the unit of heredity, and "expression," meaning the manifestation or realization of a trait. The concept emerged following the seminal discovery of DNA structure and the central dogma of molecular biology, which describes the flow of genetic information from DNA to RNA to protein. It is the core mechanism by which genetic potential is realized in a living organism.

What is the Mechanism of Gene Expression?

The process begins with transcription, where the DNA sequence of a gene is copied into messenger RNA (mRNA) by RNA polymerase. The mRNA then travels to the ribosomes where translation occurs, converting the mRNA sequence into a chain of amino acids, forming a functional protein. Steroid hormones often act as transcription factors, binding to receptors that then directly modulate the transcription phase, thereby controlling the quantity of the final protein product and altering cellular function.
