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. Capping on 5 prime end (7 methylguanosine) -






2. 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)






3. Prophas - metaphase - anaphase telophase






4. VItamin C






5. Less condensed - transciptionally active=eu truly transcobed






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






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






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






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






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






11. Brings together 2 ends of DNA fragments no requirement for homology






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






13. Inhibits by binding to the potassium side






14. Proline - glycine






15. 2 H bonds greater GC content greater melting point






16. Neurons - skeletal - and cardiac muscle - RBCs






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






18. Tansport cellular cargo toward opposite ends of microtubule tracks






19. 1 RNA polymerase (multisubunite complex) makes all 3 kinds of RNA






20. MRNA






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






22. Inhibits thymidylate synthase down thymine






23. Inhibits 50S peptidyl transferase






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






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






26. Substituting a pyramidine for a pyrimadine






27. The 3 prime end






28. GTP






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






30. Each codon specifies only 1 amino acid






31. Has enough energy to created the peptide bond






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






33. Lysine/hydroxylysine and combines to form collagen






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






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






36. 9+2 arrangement of microtubules -






37. Anterograde to microtubule






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






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






40. H1 string






41. Particular sequnece in genomre where DNA replication begins. May be single (prokaryotes) or multiple (eukaryotes)






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






43. 1P (blocked by tetracycline)






44. Uracil






45. H1






46. Bm - kidney - ears and eyes






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






48. Alpha 1 antitrypisn






49. Faulty collagen synthesis causing 1) hyperextensible skin 2) tendency to bleed 3) hypermobile joints






50. Methyl THYmine has a meTHYl
