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. Each codon specifies only 1 amino acid






2. One codon AUG






3. GTP






4. ATP






5. Remain in G0 regenerate from stem cells






6. A site - incoming aminoacyl tRNA - Psite accomodates growing Peptide - E site holds EmplytRNA as it exits






7. Substituting a purine for a pyrimdine or vice versa






8. Blocks denovo purine synthesis






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






10. Strethchy protein within lungs - large artiers - elastic liaments - vocal cords - ligamenta flava)






11. Methyl THYmine has a meTHYl






12. VItamin C






13. G1 - S - G2 - Mitosis






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






15. Bind 50S blocking translocation






16. Anit helminth - act on microtubules






17. Greater melting temperature lower fluidity






18. HS1 - HSB - H2 - H4






19. Ketone






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






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






22. Site where RNA polymerase and multiple other transciption factors bind to DNA upstream from gene locus (AT rich upstream sequence with TATA and CAAT boxes)






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






24. H1






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






26. Different exons can be combined to make nique protiens in different times






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






28. AD and AR- associated iwth joint dislocation - berry aneurysms - organ rupture






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






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






31. Even 40S 60S =80S






32. 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






33. Inhibits ribonucleotide reductase






34. The 3 prime end






35. Less condensed - transciptionally active=eu truly transcobed






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






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






38. Non homologous end joining






39. Anti breast cancer - acts on mts






40. 5 prime to 3 prime






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






42. DNA And RNA synthesized in the 5-3 direction






43. Bm - kidney - ears and eyes






44. Codes for formyl methionine (f - Met)






45. AUG inAUGurates protein synthesis






46. The N to C






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






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






49. Inhibits 50S peptidyl transferase






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