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






2. Remain in G0 regenerate from stem cells






3. Prevents stranges from reannealing






4. Inhibits by binding to the potassium side






5. Responsible for the accuracy of amino acid selection






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






7. Inhibits 50S peptidyl transferase






8. CUT 1 ring Cut the Py






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






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






11. Completed protein is released from ribosme through simple hydrolosis and dissociates






12. Intervening noncoding segments of DNA






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






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






15. ATP






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






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






18. Blocks denovo purine synthesis






19. Does not






20. Rampant - Massive - TIny rRNA is most common - then mRNA and then tRNA






21. CCA AT 3 PRIME END






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






23. Phosphorylation - glycosloation - hyderoxylation






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






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






26. Seals






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






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






29. 3 H bonds






30. Greater melting temperature lower fluidity






31. Anti breast cancer - acts on mts






32. Condensed - transciptionally inactive HC- Highly condensed






33. Unwinds DNA template at replication fork






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






35. Lysine/hydroxylysine and combines to form collagen






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






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






38. H1






39. Neuroglia






40. Anterograde to microtubule






41. 5 prime to 3 prime






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






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






44. Made from orogate precuror with PRPP added later






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






46. Less condensed - transciptionally active=eu truly transcobed






47. Three amino acids necessary for purine synthesis= glutamine - aspartate and glycine






48. Codes for formyl methionine (f - Met)






49. Antifungal - act on microtubules






50. MRNA
