The operon that controls the metabolism of lactose is called the what?
its an operon required for the transport and metabolism of lactose.
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.
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.
How many genes in the lac operon are found in e. coli?
My answer is 3, I am pretty sure I am right, but I would double check to make sure. I am in ninth grade taking biology at PineTree.
The role of a metabolite that controls a repressible operon is to?
The role of a metabolite that controls a repressible operon is to
The tryptophan operon is a repressible operon that is?
Turned off whenever tryptophan is added to the growth medium
2 types of operons?
The two types of operons are Inducible and Repressible Operons.
What is Corepressor and their function?
The metabolite that when bound to the repressor (of a repressible operon) forms a functional unit that can bind to its operator and block transcription.
The tryptophan synthetase operon uses glucose to synthesize tryptophan Repressible operons such as this one are?
turned off whenever tryptophan is added to the growth medium.
Difference between inducible and repressible operons?
The differences between these two types of operons are significant. In the repressible operon, The product is the regulatory metabolite and starts in the "on" position allowing RNA primase to unzip mRNA. Also the repressor protein only bings to the operator gene in the presence of the regulatory metablite. In the inducible operon, The reactact is the regulartory metabolite and starts in the off position blockig the primase from unzipping mRNA. The repressor protein only binds to the operator gene in the absence of the regulatory metabolite.
Synthesis of a repressible enzyme is inhibited by?
The corepressor-repressor binding to the operator stops the repressible enzyme synthesis. The rate of production of repressible enzyme can be stopped or inhibited if a substance is in high concentration.
Was a civil war an repressible or irrepressible conflict?
irrepressible
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?
When does the induction of the lac operon occur?
The lac operon is most active when glucose levels are low and lactose is present.
What turns the lac operon on and off?
The lac operon is turned off and on by repressors.
