In Figure 84 which model of the lac operon correctly shows RNA polymerase lactose and repressor protein when the structural genes are being transcribed?
regulatory promoter oerator
A protein that binds to an operator and inhibits transcription?
A repressor protein, also called an Inhibitor.
What is a gene regulation?
The regulator gene produces repressor protein.
How do repressors affect promoters?
a repressor is a protein that binds to DNA, which turns off the genes that code for the digestive enzymes. the promoter, located near the digestive enzyme genes, is a section on DNA that serves as the binding site for the enzyme RNA polymers.
When is gene expression blocked in the lac operon system?
The repressor protein blocks the genes from making mRNA.
What state is the repressor protein in when tryptophan is absent?
The repressor protein is inactive.
In Figure 84 which model of the lac operon correctly shows RNA polymerase lactose and repressor protein when the structural genes are being transcribed?
regulatory promoter oerator
A protein that binds to an operator and inhibits transcription?
A repressor protein, also called an Inhibitor.
This protein is produced by a regulatory gene?
a repressor protein
A repressor protein binds with?
The regulator
What happens to the repressor protein when it's not functioning?
When the repressor protein in not functioning then the gene that that protein was blocking will be "turned on". BTW its not right to cheat, even on study guides ;)
What is a gene regulation?
The regulator gene produces repressor protein.
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.
The presence of a repressor protein prevents the action of what enzyme?
RNA polymerase.
In prokaryotes a protein that binds to the operator and blocks the prometer is called?
Repressor
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.
Which type of molecule is DNA sequences transcribed for protein synthesis?
DNA is transcribed to Messenger RNA (mRNA), and protein coding mRNAs form proteins
