Which of the following correctly describes eukaryotic transcriptional control? a. A transcription factor is a DNA molecule that helps RNA polymerase to bind to the enhancer of a specific gene. b. An enhancer is a protein that encourages gene expression by binding to the DNA. c. The promoter is the region of RNA where DNA polymerase will bind to begin transcription. d. The interaction of multiple transcription factors may be required in order to transcribe a...
Which of the following statements is FALSE? Nucleotides are only ever linked to one another 5’ to 3’ DNA can contain Uracil as a result of a chemical reaction MutS/MutL only works to repair the lagging strand of synthesis Alternative splicing happens in every eukaryotic gene All of these statements are false The protein that phosphorylates the CTD to initiate transcription is called EF-Tu eIF4 TFIID TFIIH RNA polymerase Which of these enzymatic activities in DNA replication require the input...
DNA polymerases are processed, which means that they remain tightly associated with the while moving rapidly and adding nucleotides to the growing daughter strand. Which piece of the machinery accounts for this characteristic? (a) helicase (b) sliding elamp (c) single-strand binding protein (d) primase RNA in cells differs from in that _____ (A) it contains the base uracil, which pairs with cytosine (b) it is single stranded and cannot form base pairs (c) it is single stranded and can fold...
What are the four common core promoter elements for eukaryotic genes transcribed by RNA polymerase II? Must all of these elements be present in the promoter for transcription of every gene to occur? Explain
1. this proteins is responsible for increasing or decreasing supercoiling of DNA A. Helicase B. DNA Polymerase C. Topoisomerase D. RNA Polymerase E. DNA ligase 2. a gene is best defined as A. A segment of DNA that contains inherited information that defines the structure of a protein or RNA B. thee nucleotides that code for an amino acid C. a translated unit of DNA D. a sequence of nucleotides in RNA that codes for a functional product 3. This...
The process of DNA transcription: produces single stranded RNA complementary to the coding strand. requires RNA polymerase. is discontinuous. produces double stranded DNA. requires DNA polymerase III. Among the significant sites that many eukaryotic promoters contain is: a TATAAT box near –10. a TATA site near –30 to –100. a CATA site at the transcription start site. a Pribnow box. the Shine-Dalgarno sequence.
Can someone please help me answer these questions. Thank you! Eukaryotic transcription signals a) This drawing shows the placements of the four main sequences of the eukaryotic core promoter for RNA polymerase II. Identify each one and give a brief explanation b) Which sequences are used in a DPE-driven promoter? c) Which ones are used in a TATA-driven promoter? d) Please draw and describe the steps as the transcription factors work with eukaryotic RNA polymerase II to start transcription of...
Which one of the following is the main reason that a typical eukaryotic gene is able to respond to a far greater variety of regulatory signals than a typical prokaryotic gene or operon? A. Eukaryotes have three types of RNA polymerase. B. Eukaryotic RNA polymerases require general transcription factors. C. The transcription of a eukaryotic gene can be influenced by proteins that bind far from the promoter. D. Prokaryotic genes are packaged into nucleosomes.
