The product could be an enzyme, a structural protein, or a control molecule. Studies of gene expression typically measure the production of mRNA. Most mechanisms that control gene expression do so by controlling transcription, the synthesis of mRNA.
Definition of Gene Regulation is “the control of gene regulation and expression is very well understood in prokaryotes. The switching on and off of the gene to regulate the synthesis of various proteins (the enzymes, for example) is essential. The fluctuation in the immediate environment of the organism is coped with by such regulation”.
Gene regulation is essential for viruses, prokaryotes and eukaryotes as it ... Epigenetic modifications are also a key factor in influencing gene expression.Transcription factors are proteins that help turn specific genes "on" or "off" by binding to nearby DNA. Transcription factors that are activators boost a gene's transcription. Repressors decrease transcription. Groups of transcription factor binding sites called enhancers and silencers can turn a gene on/off in specific parts of the body.

Prokaryotes, such as bacteria, have a relatively ...16.2 Prokaryotic Gene Regulation. The regulation of gene expression in prokaryotic cells occurs at the transcriptional level. There are two majors kinds of proteins that control prokaryotic transcription: repressors and activators. Repressors bind to an operator region to block the action of RNA polymerase. Activators bind to the promoter to ...
Jun 20, 2023 · An operon is a cluster of coordinately regulated genes. It includes structural genes (generally encoding enzymes), regulatory genes (encoding, e.g. activators or repressors) and regulatory sites (such as promoters and operators). The type of control is defined by the response of the operon when no regulatory protein is present.
Compare and contrast the positive control mechanism of Model 3 with the negative control mechanisms in Models 1 and 2. In the negative a repressor protein binds to an operator and prevents a gene to be expressed.

It covers topics such as transcriptional regulation, repression, activation, and regulation of gene expression by operons.
To understand the control of gene expression, two key concepts should be understood. First, gene expression requires transcription , the process of making a messenger ribonucleic acid (mRNA) copy of the deoxyribonucleic acid (DNA) gene.
