What is promoters and an operator together called?
Operon. It contains the promoter, operator, and the structural gene.
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
Why lac operon the gene expression is switch off?
explain the regulation of gene expression in lac operon.
When a group of gene pairs act together?
A group of genes that is operated together is an Operon.
Where do proper enzymes come from?
synthesized from coded information of gene
What is promoters and an operator together called?
Operon. It contains the promoter, operator, and the structural gene.
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 does the promoter of the lac operon sac do?
The promoter region of the lac operon is where the RNA polymerase begins to bind for the transcription of the structural gene Y and Z
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
Why lac operon the gene expression is switch off?
explain the regulation of gene expression in lac operon.
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.
When a group of gene pairs act together?
A group of genes that is operated together is an Operon.
Where do proper enzymes come from?
synthesized from coded information of gene
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 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.
Is operon the sequence of bases on a gene that does not code for protein?
operon is a group of genes regulated by a single promoter and operator. . . generally all the genes (structural genes of a particular operon) regulate a specific metabolic pathway. . (eg : lac operon in bacteria; where 3 genes are regulated by a single promoter sequece which help in the catabolism of lactose). . . if you have any doubts mail me at vegi.chaitanya@gmial.com
What is the beginning of a gene is signaled by a region of DNA?
operon
