Which of the following functions are characteristic of general transcription factors in eukaryotes? Hint: there may be more than one correct response. Be sure to check all that apply. They inhibit RNA polymerase binding to the promoter and begin transcribing. They bind to other proteins or to the TATA box. They are sufficient to allow high levels of transcription. O They initiate and regulate the transcription of genes. O They bind to sequences just after the start site of transcription.
An operon is a group of genes under the control of a single promoter. Match each type of operon with the descriptions. Inducible Transcription stops when the repressor gene product is activated. Transcription occurs regardless of environmental conditions. Repressible Answer Bank Constitutive Sufficient amounts of the gene product inhibit further transcription. Transcription is turned on when a specific molecule is present.
Response elements are similar to operons in that they are controlled by a single promoter are enhancers of transcription activated by metabolic factors are not affected by steroids are silencers of transcription triggered by the presence of metal ions
Use the illustration as a reference to select the correct statements transcription factors of eukaryotic cells 00 Other transcription factor proteins Gene Enhancers Promoter 3 This protein complex makes it easier for RNA polymerase to attach to the promoter and start transcribing a gene 1 Activator proteins bind to pieces of DNA called enhancers. Their binding causes the DNA to bend, bringing them near a gene promoter, even though they may be thousands of base pairs away. RNA polymerase Activator proteins note This dagram simplifies the DNA - A 4 An insulator can stop the enhancers from binding to the promoter, if a protein called CTCF (named for the sequence CCCTC, which occurs in all insulators) binds to it. 2 Other transcription factor proteins join the activator proteins, forming a protein complex which binds to the gene promoter. Methyl groups CTCF (CCCTC-binding factor) -Insulator 5 Methylation, the addition of a methyl group to the C nudeotides, prevents CTCF ulator, enhancers…
When CAMP binds to the Catabolite Activator Protein (CAP), it causes a conformational change on the protein, which results in binding to the CAP- binding site on the DNA and molecule is known as a(n) of the lac operon. This conformational change induced by the binding of another transcription activation; allosteric effect transcription repression; binding effect translation; distortion effect mutation; interactive effect attenuation; compression effect O O O O
How would transcription be affected in eukaryotic cells if Mediator was deleted? Group of answer choices Transcription would occur, but a basal level Transcription would be unaffected with normal levels of transcript produced Transcription would be accelerated Transcription would be aborted and no transcription would take place
e table below with the word that matches the definition in the right column. regulatory proteins (transcription factors) that speed up transcription by helping RNA polymerase bind to a promoter DNA sequences that indicate where transcription of a gene by RNA polymerase begins-typically located upstream from the 5C end Proteins bound to DNA that affect when and how fast a gene is transcribed These factors slow down/shut off transcription either by preventing access to promoters or by keeping RNA polymerase from moving along the DNA strand 3 Regulatory DNA sequénces located upstream or downstream from an associated gene that enhance the transcription rate of that gene when bound to specific proteins 3A sequence of DNA that when bound to a transcription factor blocks the inappropriate effect of an enhancer on a neighboring gene
