What else can I help you with?
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.
What gene specifies a protein that binds to an operatr and physically blocks rna polymerase from binding to a promoter site?
The gene that specifies a protein known as a repressor can bind to the operator region in the DNA, physically blocking RNA polymerase from binding to the promoter site. This mechanism helps regulate gene expression by preventing transcription of the gene.
How is a promoter region different from an operator region?
A promoter region is different from an operator region in the sense that the operator region is where DNA binds, whereas the promoter region is the binding site for the RNA polymerase. These two different regions are essentially opposites.
Translation is to protein as transcription is to?
Translation is to protein as transcription is to RNA. Transcription is the process by which RNA is synthesized from DNA, while translation is the process by which proteins are synthesized from RNA.
Where does the transcription process begin in the synthesis of proteins?
The transcription process begins in the nucleus of a cell during protein synthesis.
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.
What turns off transcription by binding to the operator?
A repressor protein turns off transcription by binding to the operator region. By binding to the operator, the repressor prevents the RNA polymerase from binding to the promoter region and initiating transcription. This prevents the expression of the gene or genes downstream of the operator.
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.
How does the repressors protein prevent transcription?
By attaching to the a region of the gene called operator thus blocking RNA polymerase so that the gene is not transcribed.
What gene specifies a protein that binds to an operatr and physically blocks rna polymerase from binding to a promoter site?
The gene that specifies a protein known as a repressor can bind to the operator region in the DNA, physically blocking RNA polymerase from binding to the promoter site. This mechanism helps regulate gene expression by preventing transcription of the gene.
How is protein synthesis?
Protein synthesis occurs by the processes of transcription and translation. In transcription, the genetic code.
How is a promoter region different from an operator region?
A promoter region is different from an operator region in the sense that the operator region is where DNA binds, whereas the promoter region is the binding site for the RNA polymerase. These two different regions are essentially opposites.
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.
What are two parts of protein synthesis?
transcription and translation
What is an angiostatin?
An angiostatin is a protein which inhibits angiogenesis.
Translation is to protein as transcription is to?
Translation is to protein as transcription is to RNA. Transcription is the process by which RNA is synthesized from DNA, while translation is the process by which proteins are synthesized from RNA.
What is in transcription?
rna polymerase and protein
