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. The N to C






2. Prophas - metaphase - anaphase telophase






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






4. Elastase






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






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






7. Inhibits the atpase which increases intracellular sodium which increases intracellular calcium increases cardiaccontractility

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






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






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






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






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






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






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






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






28. Close to - far from or even within (in an intron) the gene whose expression it regulates






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

31. Enter G1 from G0 when stimulated Hepatocytes/lymphocytes






32. The 3 prime end






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






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






35. Phosphorylation - glycosloation - hyderoxylation






36. Less condensed - transciptionally active=eu truly transcobed

38. Anit helminth - act on microtubules






39. 5 prime to 3 prime






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






41. Microvilli - muscle contraction - cytokinesis - adhering juntions






42. 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
