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. Does not






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

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






24. Inhibits dihydrofolate reductase down thymine






25. Neurons






26. Antigout - acts on mts






27. Alpha 1 antitrypisn






28. Bm - kidney - ears and eyes






29. Less condensed - transciptionally active=eu truly transcobed






30. Ribonucleotide reductase






31. 1P blocked by chloramphenicaol and macrolide






32. The 3 prime hydroxyl of the nascent chain is the target






33. Anti cancer - act on microtubules






34. 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






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






36. Has enough energy to created the peptide bond






37. VItamin C






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






39. Strethchy protein within lungs - large artiers - elastic liaments - vocal cords - ligamenta flava)






40. Type III

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






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






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






45. Bind 50S blocking translocation






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






47. Bind 30S subunit preventing attachment of aminoacyl - tRNA






48. Substituting a purine for a pyrimdine or vice versa
