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. Inhibits ribonucleotide reductase






2. Unmethylated - newly synthesized string is recognized - mismatched nucleotides are removed and the gap is filled and resealed






3. ATP






4. One codon AUG






5. Stretch of DNA that alters gene expression by binding transcription factors

7. Site where negative regulators bind






8. CUT 1 ring Cut the Py






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






10. 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






11. Immotile cilia due to a dyenin arm defect. Results in male nad female inferticility (sperm immotile) - bronchiectasis - and recurrent sinusisits - associated with situs inversus






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






13. UGA - UAG - UAA






14. Muscle






15. 3 sodium out for 2 potassium in (nout - kin)takes 1 atp and the machine is phosphorylated during the machine cycle






16. Less condensed - transciptionally active=eu truly transcobed






17. Contain the actual genetic information coding for protein






18. Cyclin depndent kinases; consituative and inactive






19. 2 H bonds greater GC content greater melting point






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






21. Unattached to any membrane; site of cytosolic and organeller prtoeins






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






23. 1 RNA polymerase (multisubunite complex) makes all 3 kinds of RNA






24. Base+ribose+phosphate linked by a phosphodiester bond






25. Microvilli - muscle contraction - cytokinesis - adhering juntions






26. ATP- AMP (2 phosphoanhydride bonds)






27. Methyl THYmine has a meTHYl






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






29. 1P (blocked by tetracycline)






30. Never go to Go divide rapidly with short G1 bone marrow - gut epithelium - skin - hair follicles






31. Binds 50S blocking translocation






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






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






34. Poly adenylation






35. Ribonucleotide reductase






36. Remain in G0 regenerate from stem cells






37. Alpha 1 antitrypisn






38. Responsible for the accuracy of amino acid selection






39. Microtubule polymerization defect resulting in lowered phagocytosis. results in recurrent pyogenic infections - partial albinism and peripheral neuropathy






40. Hn RNA






41. Anterograde to microtubule






42. You glyucosolate hte pro - alpha chain lysine resudens and form procollagen (triple helix of alpha chains)






43. Inhibits 50S peptidyl transferase






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






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






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






47. Neuroglia






48. A malfunction of mismatch repair (MUt L etc..)






49. Even 40S 60S =80S






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