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






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






3. VItamin C






4. Remain in G0 regenerate from stem cells






5. RNA polymerase I makes rRNA - RNA pol II makes mRNA - RNA pol III makes tRNA






6. MRNA






7. 75-90 nucleotides - 2ary structure cloverleaf form anticodon end is opposite 3 prime aminoacyl end






8. Lysine/hydroxylysine and combines to form collagen






9. Prevents stranges from reannealing






10. Bm - kidney - ears and eyes






11. Proline - glycine






12. Type III






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






14. Methyl THYmine has a meTHYl






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






16. ATP- AMP (2 phosphoanhydride bonds)






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






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






19. Tansport cellular cargo toward opposite ends of microtubule tracks






20. Contain the actual genetic information coding for protein






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






22. Even 40S 60S =80S






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






24. The N to C






25. CCA AT 3 PRIME END






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






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






28. G1 - S - G2 - Mitosis






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






30. Prophas - metaphase - anaphase telophase






31. Odd 30S plus 50 S=70S






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






33. Exocytose procollagen into extracellylar sace






34. H1 string






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






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






37. Bind 50S blocking translocation






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






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






40. Inhibits by binding to the potassium side






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






42. Antigout - acts on mts






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






44. Enter G1 from G0 when stimulated Hepatocytes/lymphocytes






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






46. Specific glycosylases recognize and remove damaged bases - AP endonuclease cuts DNA at pyrimidne site - empty sugar is removed and the gap is filled and resealed






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






48. Made from IMP precursor






49. Anti cancer - act on microtubules






50. Non homologous end joining
