  1. An unbranched chain of ribonucleotides joined by 3’-5’ phosphodiester bonds
    RNA
  2. What subunits is RNAP made up of?
    • 2 alphas
    • beta
    • beta prime
  3. This part of RNAP identifies the promoter region
    Sigma
  4. This subunit of RNAP sticks to the DNA
    Beta prime subunit
  5. What does Rifampicin do?
    • Inhibits Beta subunit
    • stops bond formation
  6. What does actinomycin do?
    • Sticks to DNA
    • Stops it from unwinding
  7. RNA binds to DNA in this stage of transcription
    • Initiation
    • unwinds 17 bp
  8. Sigma goes away and RNA is made in this stage of transcription
    Elongation
  9. The hairpin loop is made in this stage of transcription
    Termination
  10. Transcription and translation happen at the same time in these guys
    prokaryotes
  11. How many types of RNAP are in prokaryotes?
    1
  12. These types of RNAP are in eukaryotes
    • 1-3
    • + mitochondrial
  13. This type of RNAP makes the primary transcript
    RNAP II
  14. Adding a piece of 7-methyl-guanosine to the 5’ end of mRNA is called this
    5' capping
  15. This enzyme does the 5' capping
    Guanyltransferase
  16. What does the 5' cap do?
    • protects
    • guides
    • starts translation
  17. Adding a couple hundred Adenines to the 3’ end of mRNA is called this
    Poly-A tailing
  18. The sequence of mRNA signals the whole “A-tailing”
    • Polyadenylation sequence
    • AAUAAA
  19. What does the Poly A tail do?
    • Stabalizes
    • Helps it get out of nucleus
  20. Removing the introns is called this
    Splicing
  21. This machine does the actual splicing
    Splicosome
  22. What is a splicosome made up of?
    snRNA and proteins
  23. These two things help make diverse amount of proteins from limited genes
    • Alternative splicing
    • RNA editing
  24. shoving a STOP codon into the mRNA by surprise is called this
    RNA editing
