Question Answered step-by-step Q21 Indicate the false statement: A: Transcription is more… Q21Indicate the false statement:A: Transcription is more error-prone than replication.B: Transcription produces mRNAs that serve as templates during protein synthesis by the ribosome.C: mRNAs are unstable molecules.D: In eukaryotes, RNA polymerase I transcribes transfer RNAs. Q22Indicate the true statement: A: In prokaryotes, three different RNA polymerases transcribe rRNA, tRNAs, and mRNAs.B: Open complex formation in prokaryotes occurs spontaneously in the absence of ATP.C: mRNAs are the most abundant of all RNA species.D: RNA polymerases can melt DNA at the promoters. Q23Indicate the false statement: A: Open complex formation is done by the sigma-factor, via the isomerization of two bases of the -10 element.B: Bacterial RNA polymerase can recognize gene promoters.C: The?sigma-2 and sigma-4 regions of sigma-70 recognize the -10 and -35 promoter elements, respectively.D: In bacteria, the main promoter elements are the -10 and -35 elements. Q24Indicate the true statement: A: PIC is formed by RNA polymerase II and seven general transcription factors.B: The translocase XPB opens promoter DNA in an ATP-dependent manner.C: TFIIH (CDK7) phosphorylates the CTD repeats at Serine 2.D: PIC formation starts with the recognition of the TATA box by TAF1 and TAF2. Q25Indicate the false statement: A: Phosphorylation of CTD repeats at Serine 5 serves as a docking site for capping factors.B: TBP is involved in the transcription by RNA polymerases I, II, and III.C: FACT displaces nucleosomes ahead of RNA polymerase II during elongation.D: The torpedo model for termination of transcription involves the degradation of RNA polymerase II.
