MCB RATS AND EXAM 2 QUESTIONS & ANSWERS 2024 UPDATE MCB RATS AND EXAM 2 QUESTIONS & ANSWERS 2024 UPDATE 1. The CTD (C Terminal Domain) is located in and consists of repeats of seven amino acids with the consensus sequence Tyr-Ser-Pro-Thr-Ser-Pro-Ser 2. In E.coli, transcription does NOT require 3. In eukaryotic cells, the factors that are involved in the recruitment of RNA-Pol during the transcription of most mRNAs are known as . 4. In eukaryotic cells, the RNA-Polymerase that transcribes messenger RNA (mRNA) is 5. The helicase activity that allows transcription by RNA-Pol II to start is mediated by 6. In E.coli, the core RNA-Polymerase differs from the whole enzyme (the one containing all subunits) in that the core polymerase lacks the subunit 7. The TFII factor that contains among its subunits two proteins known as XPB and XPD, each endowed with helicase activity, is " 8. By convention, the nucleotide where transcription starts is assigned a numeric value. That value is" 9. "In eukaryotic cells, transcription of the genes coding for the larger ribosomal RNAs (rRNAs) yields a large 45S pre-rRNA that is later on processed to produce the 28S, 18S, and 5.8S rRNAs" 10. In E. coli, RNA-Polymerase binds to the DNA at sequences known as Promoters 11. The first phosphorylation event affecting the CTD of the large subunit of is mediated by a kinase activity associated to 12. In the absence of sigma, the E.coli RNA-Polymerase 13. The factor that links the general transcription factors with the specific transcription factors is 14. In eukaryotic cells, the RNA-Polymerase that transcribes the 5S ribosomal RNA (rRNA) is
