An operon is a functioning unit of key nucleotide sequences of DNA including an operator, a common promoter, and one or more structural genes, which is controlled as a unit to produce messenger RNA (mRNA), in the process of transcription by an RNA polymerase. Biology. Glossary of biology terms . Meaning and definition of operator : In prokaryotic DNA, a sequence of nucleotides near the start of an operon to which an active represser can attach. The binding of the represser prevents RNA polymerase from attaching to the … noun, plural: operator genes (genetics) A segment of DNA being referred to when the repressor binds to it. As a result, the transcription of certain genes is inhibited. The function of an operator in Biology is to regulate access ofRNA polymerase to structural genes.

lac-operon – Wikipedia

This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce E.coli protein expression where the gene is under the control of the lac operator.

These are the key differences between an operator element within a structural protein‐coding region of DNA. From: pseudo‐operator in Oxford Dictionary of Biochemistry and Molecular Biology ». When a small amount of lactose is present the lac repressor will bind it causing dissociation from the DNA operator thus freeing the operon for gene expression. Lactose still prevents the repressor from binding to the operator region. But in addition, the lack of More recent models (e.g. [5]) include more biological detail . 27 May 2014 factor dissociation excludes a simple operator occupancy model for gene regulation Cell Biology Bioinformatics and Systems Biology Purine repressor (PurR) binding to multiple pur operator sequences regulates Escherichia coli and Salmonella typhimirium: Cellular and Molecular Biology.
