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. Site of dteroid synthesis and detoxification of druigs and poisons (liver hepatocytes and steroid horomore adrenal cortex)






2. Inhibits dihydrofolate reductase down thymine






3. Anterograde to microtubule






4. 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






5. GTP






6. Inhibits bacterials dihydrofolate reducatese down thymine






7. Microvilli - muscle contraction - cytokinesis - adhering juntions






8. 75-90 nucleotides - 2ary structure cloverleaf form anticodon end is opposite 3 prime aminoacyl end






9. Inhbits RNA pol II (found in death cap mushrooms)






10. A malfunction of mismatch repair (MUt L etc..)






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






12. Same aa often base change in 3rd position of codon






13. Site where negative regulators bind






14. Substituting a pyramidine for a pyrimadine






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






16. Uracil






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






18. Made from IMP precursor






19. Activated by GTP hydrolosis initiation factors help assembel the 40 S ribosomal subunites with the initiatior tRNA and are released whent he mRNA and the ribosomal subunit assemple with the complex






20. Anit helminth - act on microtubules






21. ATP- AMP (2 phosphoanhydride bonds)






22. ATP






23. Retrograde to microtubules






24. 1 RNA polymerase (multisubunite complex) makes all 3 kinds of RNA






25. Rampant - Massive - TIny rRNA is most common - then mRNA and then tRNA






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






27. Neuroglia






28. Connective tissue






29. HS1 - HSB - H2 - H4






30. Y shaped region along DNA template where leading and lagging strands are syntehsized






31. Genetic code is conserved throughout evolution






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






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






34. Remain in G0 regenerate from stem cells






35. Methyl THYmine has a meTHYl






36. The N to C






37. AUG inAUGurates protein synthesis






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






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






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






41. Splicing out of introns






42. Inhibits thymidylate synthase down thymine






43. Anti breast cancer - acts on mts






44. CCA AT 3 PRIME END






45. MRNA






46. Does not






47. P53 and RB normally inhibit g1 to S progression






48. Inhibits ribonucleotide reductase






49. Even 40S 60S =80S






50. Seals
