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. Proline - glycine






2. Tansport cellular cargo toward opposite ends of microtubule tracks






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






4. 4 high enrgy bonds






5. Uracil






6. Anti cancer - act on microtubules






7. Bind 50S blocking translocation






8. Elastase






9. Muscle






10. Neurons






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






12. Anti breast cancer - acts on mts






13. Inhibits the atpase which increases intracellular sodium which increases intracellular calcium increases cardiaccontractility






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






15. Neurons - skeletal - and cardiac muscle - RBCs






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






17. One codon AUG






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






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






20. HS1 - HSB - H2 - H4






21. Each codon specifies only 1 amino acid






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






23. Has enough energy to created the peptide bond






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






25. Methyl THYmine has a meTHYl






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






27. Poly adenylation






28. Condensed - transciptionally inactive HC- Highly condensed






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






30. The N to C






31. Greater melting temperature lower fluidity






32. Inhibits thymidylate synthase down thymine






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






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






35. GTP






36. Site where negative regulators bind






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






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






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






40. Changed aaconservative - new aa is similar in chemical structure






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






42. Antigout - acts on mts






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






44. ATP- AMP (2 phosphoanhydride bonds)






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






46. Seals






47. ATP ase that links peripheral 9 doublets and causes bending of cilium by differential sliding of doublets






48. Codes for formyl methionine (f - Met)






49. 2 H bonds greater GC content greater melting point






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