What else can I help you with?
What state is the repressor protein in when tryptophan is absent?
When tryptophan is absent, the repressor protein is in an inactive state, allowing transcription of the trp operon to continue. This is because the repressor protein needs tryptophan to bind to it, enabling it to attach to the operator region and block transcription of the operon.
The presence of a repressor protein prevents the action of what enzyme?
The presence of a repressor protein prevents the action of RNA polymerase, which is responsible for transcribing DNA into RNA. By binding to specific regions on DNA, the repressor protein inhibits RNA polymerase from accessing the gene and initiating transcription.
How is the trp repressor protein and allosteric protein?
If Tryptophan is low in the diet, the repressor changes shape and allows the RNA polymerase to attach and copy the DNA so that Tryptophan can be produced by the cell.
What is the relationship between a regulator gene and repressor protein?
A regulator gene encodes for a repressor protein, which can bind to specific DNA sequences to inhibit the expression of target genes. The repressor protein acts as a transcription factor by preventing RNA polymerase from binding to the promoter region of the target gene, thereby regulating its expression.
If a specific kind of protein is not continually used by a cell the gene for that protein is?
the gene is never expressed. ^^^^ this guy is a frickin idiot. and this would more of be in the cells/ biology section. What happens is a repressor binds to the operator and turns off the gene so the protein doesn't get made. and when its needed the repressor detaches and the gene is turned back on. ( this all happens on a strand of DNA )

This protein is produced by a regulatory gene?
a repressor protein
A repressor protein binds with?
The regulator
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.
When is the repressor protein transcribed?
The repressor protein is transcribed when the gene coding for it is activated. This often occurs in response to specific signals or conditions in the cell. The repressor protein then acts to regulate the expression of other genes in the cell by binding to specific DNA sequences.
The presence of a repressor protein prevents the action of what enzyme?
The presence of a repressor protein prevents the action of RNA polymerase, which is responsible for transcribing DNA into RNA. By binding to specific regions on DNA, the repressor protein inhibits RNA polymerase from accessing the gene and initiating transcription.

A protein that binds to an operator and inhibits transcription?
A repressor protein binds to the operator region of DNA to inhibit the binding of RNA polymerase, blocking transcription of the gene. This mechanism is common in prokaryotic organisms to regulate gene expression by preventing transcription of specific genes when they are not needed.
In prokaryotes a protein that binds to the operator and blocks the prometer is called?
Repressor

The expression of the tryptophan operon is controlled by?
The expression of the tryptophan operon is controlled by a repressor protein that binds to the operator region in the presence of tryptophan. When tryptophan levels are high, the repressor is active and prevents transcription of the operon. When tryptophan levels are low, the repressor is inactive, allowing transcription to occur.
