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. Regulatory proteins that control cell cycle events; phase specific; activated CDKs






2. ATP






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






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






5. Genetic code is conserved throughout evolution






6. Negatively charged DNA loops twice around histone octamers create a nucloesome bead.






7. The 3 prime end






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






9. Neurons - skeletal - and cardiac muscle - RBCs






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






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






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






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






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






15. Microvilli - muscle contraction - cytokinesis - adhering juntions






16. Particular sequnece in genomre where DNA replication begins. May be single (prokaryotes) or multiple (eukaryotes)






17. AUG inAUGurates protein synthesis






18. Changed aaconservative - new aa is similar in chemical structure






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






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






21. Seals






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






23. Inhibits by binding to the potassium side






24. Anit helminth - act on microtubules






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






26. ATP- AMP (2 phosphoanhydride bonds)






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






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






29. Binds 50S blocking translocation






30. Non homologous end joining






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






32. Tansport cellular cargo toward opposite ends of microtubule tracks






33. Odd 30S plus 50 S=70S






34. Has enough energy to created the peptide bond






35. Codes for formyl methionine (f - Met)






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






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






38. 1P (blocked by tetracycline)






39. Each codon specifies only 1 amino acid






40. Contain the actual genetic information coding for protein






41. Greater melting temperature lower fluidity






42. Intervening noncoding segments of DNA






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






44. Anterograde to microtubule






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






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






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






48. Site where negative regulators bind






49. The N to C






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