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.

Question 2 Select one answer. Catabolite Activator Protein (CAP): An Activator Regulator. Just as the trp operon is negatively regulated by tryptophan molecules, there are proteins that bind to the operator sequences that act as a positive regulator to turn genes on and activate them. For example, when glucose is scarce, E. coli bacteria can turn to other sugar sources for fuel. To do this, new genes to process these Start studying Biology Chapter 18.

Examples of operator in the following topics: The trp Operon: A Repressor Operon. A DNA sequence called the operator sequence is encoded between the promoter region and the first trp-coding gene. This operator contains the DNA code to which the repressor protein can bind.

'Operator', All Acronyms, 17 February 2021, [accessed 17 February 2021] Bluebook. Als Operator wird in der Genetik ein Abschnitt auf dem Operon in der Nähe oder innerhalb des Promotors bezeichnet, an den ein Regulatorprotein (Repressor oder Aktivator) binden kann und dadurch die Affinität des Promotors zur RNA-Polymerase verringert bzw. erhöht. Damit wird die Transkription der Gene im Operon reguliert. An operator that has a unique self-adjoint extension is said to be essentially self-adjoint; equivalently, an operator is essentially self-adjoint if its closure (the operator whose graph is the closure of the graph of A) is self-adjoint. In general, a symmetric operator could have many self-adjoint extensions or none at all. The operator, on the other hand, influences whether the promoter will do something, or nothing.

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.
