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. Three amino acids necessary for purine synthesis= glutamine - aspartate and glycine






2. Non homologous end joining






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






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






5. Contain the actual genetic information coding for protein






6. Microvilli - muscle contraction - cytokinesis - adhering juntions






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






8. 3 sodium out for 2 potassium in (nout - kin)takes 1 atp and the machine is phosphorylated during the machine cycle






9. H1






10. Splicing out of introns






11. Base + ribose






12. Greater melting temperature lower fluidity






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






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






15. Responsible for the accuracy of amino acid selection






16. ATP






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






18. Elastase






19. Tansport cellular cargo toward opposite ends of microtubule tracks






20. One codon AUG






21. Each codon specifies only 1 amino acid






22. 75-90 nucleotides - 2ary structure cloverleaf form anticodon end is opposite 3 prime aminoacyl end






23. Substituting a purine for a pyrimdine or vice versa






24. Antifungal - act on microtubules






25. Anti cancer - act on microtubules






26. Cyclin depndent kinases; consituative and inactive






27. Even 40S 60S =80S






28. RNA polymerase I makes rRNA - RNA pol II makes mRNA - RNA pol III makes tRNA






29. Genetic bone disorder (brittle bone disease) type 1 colalgen - fractures (during birth) 2) Blue sclerae 3) hearing loss 4) dental imperfections 1:10000 may be confused with child abuse






30. Bm - kidney - ears and eyes






31. Substituting a pyramidine for a pyrimadine






32. Less condensed - transciptionally active=eu truly transcobed






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






34. Binds 50S blocking translocation






35. Antigout - acts on mts






36. Prevents stranges from reannealing






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






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






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






40. 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






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






42. Neuroglia






43. UGA - UAG - UAA






44. 2 H bonds greater GC content greater melting point






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






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






47. 4 high enrgy bonds






48. Anti breast cancer - acts on mts
