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. 1P blocked by chloramphenicaol and macrolide






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






3. Lysine/hydroxylysine and combines to form collagen






4. Methyl THYmine has a meTHYl






5. Proline - glycine






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






7. Retrograde to microtubules






8. Brings together 2 ends of DNA fragments no requirement for homology






9. Unwinds DNA template at replication fork






10. Has enough energy to created the peptide bond






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






12. Anit helminth - act on microtubules






13. Odd 30S plus 50 S=70S






14. 1P (blocked by tetracycline)






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






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






17. One codon AUG






18. Made from orogate precuror with PRPP added later






19. Anti cancer - act on microtubules






20. Uracil






21. Microvilli - muscle contraction - cytokinesis - adhering juntions






22. Tansport cellular cargo toward opposite ends of microtubule tracks






23. Specific endonucleases release the oligonucleotide containing damaged bases. DNA polymerase and logase fill and resealt eh gap






24. Accurate base pairing is required only in the first 2 nucleotide positions of an mRNA so codons differing ht e3rd wobble psoition may code for the same tRNA/amino acid code






25. Substituting a purine for a pyrimdine or vice versa






26. Remain in G0 regenerate from stem cells






27. ATP- AMP (2 phosphoanhydride bonds)






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






29. AD and AR- associated iwth joint dislocation - berry aneurysms - organ rupture






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






31. The N to C






32. Site of secretory protiens (mucus secreting goblet cells and antibody secreting cells)






33. Seals






34. Hydroxy proline and hydroxylysine






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






36. Anti breast cancer - acts on mts






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






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






39. Connective tissue






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






41. Responsible for the accuracy of amino acid selection






42. 5 prime to 3 prime






43. Muscle






44. Blocks denovo purine synthesis






45. Greater melting temperature lower fluidity






46. Cleave terminal regions of procollagen to transform into insoluable tropocolagen






47. Codes for formyl methionine (f - Met)






48. Neuroglia






49. 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






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