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. Alpha 1 antitrypisn






2. Anterograde to microtubule






3. Xlinked recessive IV collagen bm - kidney - ear and eye -- nephritis and defness ocular disturbances






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






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






6. Cyclin depndent kinases; consituative and inactive






7. More than 1 codon may code for the same amino acid






8. Neurons - skeletal - and cardiac muscle - RBCs






9. Blocks denovo purine synthesis






10. Regulatory proteins that control cell cycle events; phase specific; activated CDKs






11. Muscle






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






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






14. Epithelial cells






15. CUT 1 ring Cut the Py






16. Commonly results in dramatic decrease in amount of gene transcribed






17. Genetic code is conserved throughout evolution






18. Ketone






19. The 3 prime hydroxyl of the nascent chain is the target






20. Even 40S 60S =80S






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






22. Prokaryotic only. Degrades RNA primer and fills in the gap with DNA (5 prime to 3 prime exonuclease)






23. 3 H bonds






24. Anti breast cancer - acts on mts






25. Three amino acids necessary for purine synthesis= glutamine - aspartate and glycine






26. Made from IMP precursor






27. Neuroglia






28. Specific endonucleases release the oligonucleotide containing damaged bases. DNA polymerase and logase fill and resealt eh gap






29. Substituting a purine for a pyrimdine or vice versa






30. Tansport cellular cargo toward opposite ends of microtubule tracks






31. Inhibits 50S peptidyl transferase






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






33. Cilia - glagella - mitotic spindle - neurons - centrioles






34. GTP






35. Intervening noncoding segments of DNA






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






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






38. Responsible for the accuracy of amino acid selection






39. 1P blocked by chloramphenicaol and macrolide






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






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






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






43. Bm - kidney - ears and eyes






44. 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






45. Methyl THYmine has a meTHYl






46. Mutation in nucleotide excision repair Dry skin with melanoma and other cancers






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






48. Inhibits ribonucleotide reductase






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






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