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. Has enough energy to created the peptide bond






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






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






4. Attachment of ubiquitin to defective proteinds to tag them for breakdown






5. H1 string






6. Site where negative regulators bind






7. Nucleotide excision repair - Base Excision repair - Mismath repair






8. Scrutinizes aa before and after it binds to tRNA. If incorrect bond is hydrolyzed.






9. 75-90 nucleotides - 2ary structure cloverleaf form anticodon end is opposite 3 prime aminoacyl end






10. Bm - kidney - ears and eyes






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






12. Elastase






13. H1






14. The 3 prime end






15. Hn RNA






16. UGA - UAG - UAA






17. 1 RNA polymerase (multisubunite complex) makes all 3 kinds of RNA






18. Methionine - which may be removed before translation is completed






19. Each codon specifies only 1 amino acid






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






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






22. 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






23. Retrograde to microtubules






24. GTP






25. ATP- AMP (2 phosphoanhydride bonds)






26. Must be both activated and inactivated for cell cycle to progress






27. Inhibit DNA gyrase (specific prokaryotic topoisomerase)






28. Epithelial cells






29. G1 - S - G2 - Mitosis






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






31. Enter G1 from G0 when stimulated Hepatocytes/lymphocytes






32. Anti breast cancer - acts on mts






33. Genetic code is conserved throughout evolution






34. Binds 50S blocking translocation






35. Microvilli - muscle contraction - cytokinesis - adhering juntions






36. Be So Totatally Cool Read Books (bOne - CarTWOlage - Threeticular - Type IV under the floor)






37. Asymmetric fluid bilayer - contains - cholesterol - phospholipids - sphingoplipids - glycolipids - and protiends






38. Poly adenylation






39. (A - G) 2 rings Pure As Gold






40. Less condensed - transciptionally active=eu truly transcobed






41. Read froma fixed starting point as a continous sequenecs of bases






42. Antigout - acts on mts






43. Intervening noncoding segments of DNA






44. Anti cancer - act on microtubules






45. Genetic bone disorder (brittle bone disease) type 1 colalgen - fractures (during birth) 2) Blue sclerae 3) hearing loss 4) dental imperfections 1:10000 may be confused with child abuse






46. RNA polymerase I makes rRNA - RNA pol II makes mRNA - RNA pol III makes tRNA






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






48. RER translation of collagen alpha chains (preprocollagen) usually Gly-X-Y






49. 1P (blocked by tetracycline)






50. Ribonucleotide reductase
