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. Lysine/hydroxylysine and combines to form collagen






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






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






4. Antigout - acts on mts






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






6. Enter G1 from G0 when stimulated Hepatocytes/lymphocytes






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






8. Prokaryotic only. Elongates leading strand by adding deoxynucleotides to the 3prime end. Elongates laggin strand. 3 prime to 5 prime exonuclease activity






9. P53 and RB normally inhibit g1 to S progression






10. Change resulting in early stop codon






11. Prophas - metaphase - anaphase telophase






12. Hn RNA






13. 1P blocked by chloramphenicaol and macrolide






14. 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






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






16. Inhibits bacterials dihydrofolate reducatese down thymine






17. Site where RNA polymerase and multiple other transciption factors bind to DNA upstream from gene locus (AT rich upstream sequence with TATA and CAAT boxes)






18. More than 1 codon may code for the same amino acid






19. Phosphorylation - glycosloation - hyderoxylation






20. 1 RNA polymerase (multisubunite complex) makes all 3 kinds of RNA






21. ATP- AMP (2 phosphoanhydride bonds)






22. Bind 50S blocking translocation






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






24. Less condensed - transciptionally active=eu truly transcobed






25. Read froma fixed starting point as a continous sequenecs of bases






26. The N to C






27. 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






28. Type III






29. Mutation in nucleotide excision repair Dry skin with melanoma and other cancers






30. Blocks denovo purine synthesis






31. Inhibits ribonucleotide reductase






32. RER translation of collagen alpha chains (preprocollagen) usually Gly-X-Y






33. Cilia - glagella - mitotic spindle - neurons - centrioles






34. 3 H bonds






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






36. 9+2 arrangement of microtubules -






37. Uracil






38. Immotile cilia due to a dyenin arm defect. Results in male nad female inferticility (sperm immotile) - bronchiectasis - and recurrent sinusisits - associated with situs inversus






39. MRNA






40. Neurons






41. Ribonucleotide reductase






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






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






44. 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






45. Proline - glycine






46. Poly adenylation






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






48. ATP






49. Genetic bone disorder (brittle bone disease) type 1 colalgen - fractures (during birth) 2) Blue sclerae 3) hearing loss 4) dental imperfections 1:10000 may be confused with child abuse






50. DNA And RNA synthesized in the 5-3 direction
