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. Muscle






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






3. One codon AUG






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






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






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






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






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






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






10. Cylindrical structure composed of helical array of plymerized dimers of alpha and beta tubulin - flagella - cilia - mitotic spindle - grows slowly collapses quickly






11. Proline - glycine






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






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






14. Anterograde to microtubule






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






16. Non homologous end joining






17. The N to C






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






19. Poly adenylation






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






21. Methyl THYmine has a meTHYl






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






23. Seals






24. Enter G1 from G0 when stimulated Hepatocytes/lymphocytes






25. Inhibits bacterials dihydrofolate reducatese down thymine






26. HS1 - HSB - H2 - H4






27. 75-90 nucleotides - 2ary structure cloverleaf form anticodon end is opposite 3 prime aminoacyl end






28. 5 prime to 3 prime






29. CCA AT 3 PRIME END






30. Tansport cellular cargo toward opposite ends of microtubule tracks






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






32. Phosphorylation - glycosloation - hyderoxylation






33. Cyclin depndent kinases; consituative and inactive






34. 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)






35. Epithelial cells






36. Splicing out of introns






37. Change resulting in early stop codon






38. Prevents stranges from reannealing






39. 1P (blocked by tetracycline)






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






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






42. Genetic code is conserved throughout evolution






43. 3 H bonds






44. Greater melting temperature lower fluidity






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






46. Less condensed - transciptionally active=eu truly transcobed






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






48. Microvilli - muscle contraction - cytokinesis - adhering juntions






49. Inhibits ribonucleotide reductase






50. Makes an RNA primer on which DNA polymerase II can initiate replication
