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






2. 2 H bonds greater GC content greater melting point






3. Binds 50S blocking translocation






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






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






6. The 3 prime end






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






8. Condensed - transciptionally inactive HC- Highly condensed






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






10. Anit helminth - act on microtubules






11. Muscle






12. Greater melting temperature lower fluidity






13. Codes for formyl methionine (f - Met)






14. Retrograde to microtubules






15. Hydroxy proline and hydroxylysine






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






17. Microvilli - muscle contraction - cytokinesis - adhering juntions






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






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






20. Substituting a pyramidine for a pyrimadine






21. 5 prime to 3 prime






22. Inhibits bacterials dihydrofolate reducatese down thymine






23. Neurons - skeletal - and cardiac muscle - RBCs






24. G1 - S - G2 - Mitosis






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






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






27. CCA AT 3 PRIME END






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






29. 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






30. Responsible for the accuracy of amino acid selection






31. Substituting a purine for a pyrimdine or vice versa






32. Antifungal - act on microtubules






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






34. Less condensed - transciptionally active=eu truly transcobed






35. Unwinds DNA template at replication fork






36. 4 high enrgy bonds






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






38. Splicing out of introns






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






40. Cyclin depndent kinases; consituative and inactive






41. Enter G1 from G0 when stimulated Hepatocytes/lymphocytes






42. 1P blocked by chloramphenicaol and macrolide






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






44. Connective tissue






45. Ketone






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






47. Proline - glycine






48. Phosphorylation - glycosloation - hyderoxylation






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






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