An operon is actually a functioning unit of genomic DNA that contains a cluster of genes under the control of a single regulatory signal or a prometer. The genes are translated together in the cytoplasm.

What is the difference between an operon and a regulon?
1. For operon genes are located near each other. For regulon genes are present distinct site of DNA. 2. Operon may have specific operator for all genes. For regulon each gene have different operator.
Is operon proteins?
Operon is not a protein. It is a segment of DNA that has cluster of genes controlled by the elements such as promoter, operator. Lac operon is a classic example where it regulate the utilization of Lactose in the medium.
Molecules that interact with DNA to alter gene expression are?
operon
What is lac operon in E. coli?
The lac operon is a place on the DNA that binds to the DNA to stop the production of the RNA sequence to code for lactase (breaks down lactose) or binds to lactase to let the production of the RNA sequence to proceed.
The operon that controls the metabolism of lactose is called the what?
its an operon required for the transport and metabolism of lactose.

What is the beginning of a gene is signaled by a region of DNA?
operon

What happen to lac repressor in E. coli when lactose is present?
E. coli binds with lactose which changes its conformation so that it no longer binds to DNA. This allows the lactose operon to be transcribed.
An operon is composed of?
An operon is a group of genes that operate together.Operon- a functioning unit of genomic DNA containing a cluster of genes under the control of a single regulatory signal or promoter.Operons are clusters of genes consisting of one operator and promoter. There are a lac operon, which is responsible for metabolism of glucose. And there is also the Trp operon, which is responsible for synthesising tryptophan.
How many promoters are there in the entire operon?
A gene can have 100 -1000 promoters. A promoter is the region of the DNA that initiates transcription of a particular gene.
What is the role of operons in prokaryotic organisms?
An operon is a series of genes that code for specific products and the regulatory elements that control operator DNA segments.
What is lac operon in E. coli?
The lac operon is a place on the DNA that binds to the DNA to stop the production of the RNA sequence to code for lactase (breaks down lactose) or binds to lactase to let the production of the RNA sequence to proceed.
The operon that controls the metabolism of lactose is called the what?
its an operon required for the transport and metabolism of lactose.
What acts as an on and off switch in an operon?
which part of an operon acts as the on or off switch?
