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. Retrograde to microtubules






2. Substituting a pyramidine for a pyrimadine






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






4. Aminoacyl - tRNA binds to A site 2) peptidyltransferase catalyzes peptide bond formation transfers growing polypeptie to amino acid in A site 3) ribosome advances 3 nucleotides toward the 3 prime end of RNA moving peptiydyl RNA to P site






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






6. Neuroglia






7. Intervening noncoding segments of DNA






8. Site where negative regulators bind






9. Change resulting in early stop codon






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






11. Phosphorylation - glycosloation - hyderoxylation






12. H1 string






13. AD and AR- associated iwth joint dislocation - berry aneurysms - organ rupture






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






15. Substituting a purine for a pyrimdine or vice versa






16. 1 RNA polymerase (multisubunite complex) makes all 3 kinds of RNA






17. Ketone






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






19. Does not






20. Remain in G0 regenerate from stem cells






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






22. Splicing out of introns






23. Mutation in nucleotide excision repair Dry skin with melanoma and other cancers






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






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






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






27. Site where RNA polymerase and multiple other transciption factors bind to DNA upstream from gene locus (AT rich upstream sequence with TATA and CAAT boxes)






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






29. 4 high enrgy bonds






30. Unwinds DNA template at replication fork






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






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






33. Neurons - skeletal - and cardiac muscle - RBCs






34. Non homologous end joining






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






36. 75-90 nucleotides - 2ary structure cloverleaf form anticodon end is opposite 3 prime aminoacyl end






37. Accurate base pairing is required only in the first 2 nucleotide positions of an mRNA so codons differing ht e3rd wobble psoition may code for the same tRNA/amino acid code






38. Faulty collagen synthesis causing 1) hyperextensible skin 2) tendency to bleed 3) hypermobile joints






39. 9+2 arrangement of microtubules -






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






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






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






43. Prophas - metaphase - anaphase telophase






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






45. Seals






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






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






48. Lysine/hydroxylysine and combines to form collagen






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






50. Responsible for the accuracy of amino acid selection
