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.

10. Antifungal - act on microtubules






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






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






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






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






15. 1P blocked by chloramphenicaol and macrolide






16. Neurons - skeletal - and cardiac muscle - RBCs

30. One codon AUG






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






32. Checkpoints control transition between phases of cell cycle. regulated by cyclins - CDKs and tumor suppressors. Mitosis (shortest phse)






33. 4 high enrgy bonds






34. 3 sodium out for 2 potassium in (nout - kin)takes 1 atp and the machine is phosphorylated during the machine cycle






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

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






42. Inhibits by binding to the potassium side






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






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






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






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