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






2. Blocks denovo purine synthesis






3. Anit helminth - act on microtubules






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






5. Create a nick in the helix to relieve supercoils created during replication






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






7. Anterograde to microtubule






8. 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






9. Contain the actual genetic information coding for protein






10. Unattached to any membrane; site of cytosolic and organeller prtoeins






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






12. 1P blocked by chloramphenicaol and macrolide






13. 4 high enrgy bonds






14. Splicing out of introns






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






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






17. Remain in G0 regenerate from stem cells






18. Prevents stranges from reannealing






19. Made from orogate precuror with PRPP added later






20. Ketone






21. CCA AT 3 PRIME END






22. 1 RNA polymerase (multisubunite complex) makes all 3 kinds of RNA






23. Inhibits thymidylate synthase down thymine






24. Odd 30S plus 50 S=70S






25. 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






26. Trimming removal of n or c terminal propeptides from zymogens to generate mature proteinds






27. 2 H bonds greater GC content greater melting point






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






29. Regulatory proteins that control cell cycle events; phase specific; activated CDKs






30. HS1 - HSB - H2 - H4






31. Inhibits 50S peptidyl transferase






32. Prophas - metaphase - anaphase telophase






33. 9+2 arrangement of microtubules -






34. Greater melting temperature lower fluidity

36. 3 H bonds






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






38. Has enough energy to created the peptide bond






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






40. Bind 50S blocking translocation






41. Cylindrical structure composed of helical array of plymerized dimers of alpha and beta tubulin - flagella - cilia - mitotic spindle - grows slowly collapses quickly






42. 5 prime to 3 prime






43. The N to C
