Who was the operon model of the regulation of gene expression in bacteria was proposed by?
In 1961 Jacob and Monod proposed the operon model of gene regulation
What does the operon model attempt explain?
the coordinated control of gene expression in bacteria
What genes is not a part of the lac operon?
repressor gene
What is a non polar mutation?
a mutation in a gene that does not affect the downstream genes in an operon. ie. a polar mutation is one that DOES affect the transcription or translation of genes in the same operon downstream of your gene of interest.
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.
Why lac operon the gene expression is switch off?
explain the regulation of gene expression in lac operon.
Who was the operon model of the regulation of gene expression in bacteria was proposed by?
In 1961 Jacob and Monod proposed the operon model of gene regulation
What is involved in regulating gene expression in prokaryotes but not in eukaryotes?
The regulation of gene expression allows prokaryotic cells, such as bacteria, to better respond to stimuli and to conserve energy and materials
Molecules that interact with DNA to alter gene expression are?
operon
What does the operon model attempt explain?
the coordinated control of gene expression in bacteria
What is the lac operon in E. coli a classic example of?
gene expression occurring at transcription
How prokaryotes control gene expression?
The operon often controls the transcription of prokaryote genes.
When a group of gene pairs act together?
A group of genes that is operated together is an Operon.
What region of the operon does the repressor bind to?
I assume you mean the lac operon. The repressor binds upstream of the gene(s) in the regulatory gene region.
The operon segment composed of the gene that codes for a protein repressor is called the?
The operon segment composed of the gene that codes for a protein repressor is called the regulatory gene. This gene produces the repressor protein that can bind to the operator region of the operon, preventing transcription of the structural genes when the repressor is bound.
What is the beginning of a gene is signaled by a region of DNA?
operon
What information is coded by the structural gene of the operon?
proteins
