Answer) repressor / overlapping
The type of regulator that binds an operator is called a(n) repressor and usually binds to a sequence on the DNA located overlapping the RNA polymerase binding site.
(a repressor is a DNA- or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers. A DNA-binding repressor blocks the attachment of RNA polymerase to the promoter, thus preventing transcription of the genes into messenger RNA. )

The LacI protein is released from the operator sequence upon binding of IPTG, allowing the transcription of all the genes within the lac operon. In this case, LacI is called a transcriptional _______. In comparison, CRP binds to the CRP binding site sequence upon binding of cAMP, enhancing transcription. CRP is called a transcriptional _______. Select one: a. activator ;;;;; activator b. activator ;;;;; repressor c. repressor ;;;;; activator d. repressor ;;;;; repressor e. None of these

The trp operon is considered to be repressible because: 1.The repressor binds to the operator, blocking RNA polymerase from transcribing, unless tryptophan is ABSENT 2.The repressor binds to the operator, blocking RNA polymerase from transcribing, unless tryptophan is PRESENT 3.The repressor binds to RNA polymerase at the promoter to help it find the -10 sequence 4.The trp operon has five genes that code for enzymes needed to synthesize tryptophan, only expressed when trp is PRESENT

Suppose there is a protein "A" which binds to a DNA sequence and increases transcription of the gene CBC23. In the presence of molecule "C", protein "A" changes structure and can no longer bind to the DNA sequence, resulting in reduced transcription of CBC23. What terms describe "A" and "C" respectively? Enhancer and activator Repressor and Effector Effector and activator Activator and enhancer Polymerase and activator Activator and effector

How does the Trp repressor prevents RNA polymerase from initiating transcription? by blocking the ribosome binding site by forming a loop in the operator that restricts the passage of the polymerase by binding to the polymerase to inhibit its catalytic activity by physically blocking the DNA binding site of RNA polymerase

A protein binds a DNA sequence downstream of a promoter. This results in an increased rate of transcription of the gene. Which of the following site is likely to be attached? a. Operon b. Terminator c. Activator binding site d. Promotor The following are produced by algae To prepare the insert for the gene cloning, you need to find a proper source of the DNA fragment.
