REGULATOR GENE Meaning and
Definition
-
A regulatory gene, also known as a gene regulator, is a segment of DNA that controls the expression of other genes within an organism. It plays a crucial role in regulating the activity of other genes by either activating or repressing their expression. This type of gene controls the rate and level of gene transcription, ultimately affecting various cellular processes such as growth, development, and metabolism.
Regulatory genes are typically found in the regions of DNA adjacent to the genes they regulate, and they contain specific DNA sequences that are recognized and bound by transcription factors, which are proteins that control gene expression. These transcription factors can either enhance or inhibit the binding of RNA polymerase to the promoter region of a gene, thereby influencing the transcription process.
The activation or repression of genes by regulatory genes is crucial for maintaining the balance and coordination of cellular functions. For example, during embryonic development, regulatory genes guide the differentiation of cells into specific tissues and organs, ensuring proper development. Additionally, regulatory genes are also involved in responding to environmental stimuli, allowing organisms to adapt to different conditions.
Mutations or alterations in regulatory genes can lead to abnormal gene expression, which can result in various diseases or developmental defects. The study of these genes and their regulation has provided valuable insights into the mechanisms behind gene expression and its impact on overall organismal biology.

Etymology of REGULATOR GENE
The word "regulator gene" is a compound term combining the words "regulator" and "gene".
The noun "regulator" derives from the verb "regulate", which comes from the Latin word "regulare", meaning "to direct or control". It entered English in the late 17th century and originally meant "a rule or principle for guidance or control". Over time, it gained the meaning of "a person or thing that controls or manages something".
The word "gene" is derived from the German word "Gen", coined by Wilhelm Johannsen in the early 20th century. Johannsen used this term to denote the basic unit of heredity, which was later identified as segments of DNA that encode specific traits.
The compound term "regulator gene" refers to a gene that controls the expression of one or more other genes.
