I believe the correct answer to be:
FALSE.
As polyadenylation occurs after the transcription so there is no need to bind to its site before that.
feel free to leave a comment down below for any further query. good rating would be appretiated if you find my answer helpful. thank you.
True or False? A transcription factor initially binds to Poly (A) site to initiate transcription.
When a stop codon is in place at the ribosomal A site, a ________________ factor binds to the site instead of a new aminoacyl-tRNA. List two specific causes of DNA mutations. One of the ways chromatin remodeling occurs to allow gene expression is ____________________ of ______________ residues of histones. During translation, elongation factors EF-Tu and EF-G use hydrolysis of the energy molecule ________ to successfully complete their tasks The __________________________________ sequence is a consensus sequence (in prokaryotic mRNAs only) that signals...
TBP-associated factors proteins bind to promoters to help recruit RNA polymerase and initiate transcription. a. true. b. false
17) Once a protein binds to DNA at a specific site a) Transcription may be blocked b) RNA polymerase may bind more efficiently c) RNA polymerase may be unable to transcribe the gene d) Transcription may be activated e) All of these choices may result
2. a) Sketch a eukaryotic gene (brns) that is regulated by one transcription factor - Brt - that bind 50 bps upstream of the transcription start site and an enhancer - Ned - that binds 10 kb upstream of the transcription start site. In your sketch, indicate the start of transcription, TATA box beginning of the open reading frame for your gene (ATG), location of the promoter, location of the transcription factors, location of the RNA polymerase II, location of...
25. What binds to a stop codon on a mRNA during translation? a. transcription factor c. termination factor b. tRNA d. transcription initiator 26. What is typically attached to the acceptor end of a tRNA? a. a protein b. an amino acid C a ribosome d. a nucleosome 27. During mRNA processing, what is put on the 3' end of a primary mRNA transcript? a. a poly-A tail b. a cap d. an intron c. an exon 28. Which of...
termination factor A bacterial protein called rho factor binds to an mRNA at the rut site it moves along the RNA polymerase in a 5-to-3" direction chasing after the mRNA When it reaches the hairpin loop it removes it and then proceeds to break through the hydrogen bonds holding the RNA-DNA together, which successfully removes the RNA polymerase. TATA box 3-10-5 DNA-DNA rho site RNARNA
If a protein binds to a DNA sequence downstream of a promoter, transcription is enhanced. Which site is likely to be attached?
QUESTION 1 RNA poll initiates synthesis of the mRNA transcript without a primer True O False QUESTION 2 En The +1 position identifies the location for translation to begin when bound the mRNA is bound by the ribosomal subunit. True False QUESTION 3 The small ribosomal subunit binds the mRNA transcript at a sequence that is complementary to the gene promoter in order to initiate translation. O True False QUESTION 4 The 5' cap is necessary for protection from exonuclease...
