Test your basic knowledge |

First Aid: Biochemistry Molecular

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Be So Totatally Cool Read Books (bOne - CarTWOlage - Threeticular - Type IV under the floor)






2. Inhibit formation of the initation complex and cause misreading of mRNA






3. The 5prime end (energy for the bond)






4. Cylindrical structure composed of helical array of plymerized dimers of alpha and beta tubulin - flagella - cilia - mitotic spindle - grows slowly collapses quickly






5. Hydroxy proline and hydroxylysine






6. Capping on 5 prime end (7 methylguanosine) -






7. Makes an RNA primer on which DNA polymerase II can initiate replication






8. Specific glycosylases recognize and remove damaged bases - AP endonuclease cuts DNA at pyrimidne site - empty sugar is removed and the gap is filled and resealed






9. Tansport cellular cargo toward opposite ends of microtubule tracks






10. Neurons






11. Inhibits 50S peptidyl transferase






12. Contain the actual genetic information coding for protein






13. Changed aaconservative - new aa is similar in chemical structure






14. Has enough energy to created the peptide bond






15. Intervening noncoding segments of DNA






16. Vimentin - desmin - cytockeratin - glial fibrillary acid proteins - neurofilaments






17. Connective tissue






18. Type III






19. Introns stay In the nucleus whereas EXons EXit and are EXpressed






20. Anit helminth - act on microtubules






21. Trimming removal of n or c terminal propeptides from zymogens to generate mature proteinds






22. Inhbits RNA pol II (found in death cap mushrooms)






23. 1) primary transcript combines with snRNPs and other proteins to form spliceosome 2) lariat shaped intermediate is generated 3) Lariat is removed and released to precisely join 2 exons






24. Neurons - skeletal - and cardiac muscle - RBCs






25. Site of secretory protiens (mucus secreting goblet cells and antibody secreting cells)






26. Rampant - Massive - TIny rRNA is most common - then mRNA and then tRNA






27. Close to - far from or even within (in an intron) the gene whose expression it regulates






28. Inhibits the atpase which increases intracellular sodium which increases intracellular calcium increases cardiaccontractility






29. Inhibits bacterials dihydrofolate reducatese down thymine






30. Particular sequnece in genomre where DNA replication begins. May be single (prokaryotes) or multiple (eukaryotes)






31. Epithelial cells






32. Promoter - enhancer - promoter - TATA- transcription initiation site - coding region (including exons and introns) and then the AATAAA






33. Ribonucleotide reductase






34. 4 high enrgy bonds






35. 9+2 arrangement of microtubules -






36. Same aa often base change in 3rd position of codon






37. Antigout - acts on mts






38. Y shaped region along DNA template where leading and lagging strands are syntehsized






39. Change resulting in misreading of all nucleotides downstream - usually resulting in a truncated non functional protien






40. Cleave terminal regions of procollagen to transform into insoluable tropocolagen






41. 5 prime to 3 prime






42. No proofreading function but can initiate chains. RNA poymerase II opens DNA at promoter site






43. 2 H bonds greater GC content greater melting point






44. Bind 30S subunit preventing attachment of aminoacyl - tRNA






45. Cyclin depndent kinases; consituative and inactive






46. GTP






47. Condensed - transciptionally inactive HC- Highly condensed






48. Odd 30S plus 50 S=70S






49. Create a nick in the helix to relieve supercoils created during replication






50. Less condensed - transciptionally active=eu truly transcobed
