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. Remain in G0 regenerate from stem cells






2. Made from IMP precursor






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






4. Neuroglia






5. Poly adenylation






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






7. Does not






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






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






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






11. Inhibits 50S peptidyl transferase






12. 3 sodium out for 2 potassium in (nout - kin)takes 1 atp and the machine is phosphorylated during the machine cycle






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






14. Inhibits ribonucleotide reductase






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






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






17. Anti breast cancer - acts on mts






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






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






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






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






22. UGA - UAG - UAA






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






24. Alpha 1 antitrypisn






25. Inhibits dihydrofolate reductase down thymine






26. Xlinked recessive IV collagen bm - kidney - ear and eye -- nephritis and defness ocular disturbances






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






28. Methyl THYmine has a meTHYl






29. Unmethylated - newly synthesized string is recognized - mismatched nucleotides are removed and the gap is filled and resealed






30. Made from orogate precuror with PRPP added later






31. P53 and RB normally inhibit g1 to S progression






32. Seals






33. Base + ribose






34. One codon AUG






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






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






37. 5 prime to 3 prime






38. (A - G) 2 rings Pure As Gold






39. Blocks denovo purine synthesis






40. Trimming removal of n or c terminal propeptides from zymogens to generate mature proteinds






41. Microtubule polymerization defect resulting in lowered phagocytosis. results in recurrent pyogenic infections - partial albinism and peripheral neuropathy






42. Vimentin - desmin - cytockeratin - glial fibrillary acid proteins - neurofilaments






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






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






45. Bm - kidney - ears and eyes






46. Checkpoints control transition between phases of cell cycle. regulated by cyclins - CDKs and tumor suppressors. Mitosis (shortest phse)






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






48. 3 H bonds






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






50. DNA And RNA synthesized in the 5-3 direction
