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. Retrograde to microtubules






2. Change resulting in early stop codon






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






4. Inhibits thymidylate synthase down thymine






5. Prevents stranges from reannealing






6. Type III






7. H1






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






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






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






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






12. Antifungal - act on microtubules






13. The 3 prime end






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






15. Site where negative regulators bind






16. Prophas - metaphase - anaphase telophase






17. HS1 - HSB - H2 - H4






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






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






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






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






22. GTP






23. Each codon specifies only 1 amino acid






24. Does not






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






26. 4 high enrgy bonds






27. Prokaryotic only. Elongates leading strand by adding deoxynucleotides to the 3prime end. Elongates laggin strand. 3 prime to 5 prime exonuclease activity






28. Negatively charged DNA loops twice around histone octamers create a nucloesome bead.






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






30. Lysine/hydroxylysine and combines to form collagen






31. Muscle






32. VItamin C






33. 5 prime to 3 prime






34. Activated by GTP hydrolosis initiation factors help assembel the 40 S ribosomal subunites with the initiatior tRNA and are released whent he mRNA and the ribosomal subunit assemple with the complex






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






36. CUT 1 ring Cut the Py






37. Inhibits 50S peptidyl transferase






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






39. Inhibit DNA gyrase (specific prokaryotic topoisomerase)






40. Inhibits bacterials dihydrofolate reducatese down thymine






41. 1P blocked by chloramphenicaol and macrolide






42. Less condensed - transciptionally active=eu truly transcobed






43. In the nucleus after transcitpion and only processed RNA is transporte out of the nucleus






44. AUG inAUGurates protein synthesis






45. ATP






46. Microvilli - muscle contraction - cytokinesis - adhering juntions






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






48. Site of dteroid synthesis and detoxification of druigs and poisons (liver hepatocytes and steroid horomore adrenal cortex)






49. Inhibits ribonucleotide reductase






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