What is the Meaning of Gene Expression?

Gene expression is the intricate process by which the information encoded within a gene's DNA sequence is converted into a functional gene product, such as a protein or a non-coding RNA molecule. This process is the molecular mechanism underlying all cellular differentiation and function, dictating which proteins are made, in what quantity, and when. Hormones serve as master regulators of gene expression, translating external and internal signals into changes in cellular behavior.

What is the Origin of Gene Expression?

The concept emerged from the foundational work of molecular biology in the mid-20th century, specifically the discovery of the DNA double helix and the subsequent elucidation of the central dogma: DNA makes RNA, and RNA makes protein. Gene itself comes from the Greek genos (birth, race, kind).

What is the Mechanism of Gene Expression?

The process begins with transcription, where the DNA sequence is copied into messenger RNA (mRNA) within the nucleus. The mRNA then moves to the cytoplasm, where it undergoes translation by ribosomes to synthesize a specific protein. Hormones often modulate this process by binding to nuclear receptors, forming a complex that directly interacts with regulatory regions of DNA, thereby initiating or suppressing the transcription of specific target genes.
