DSST Biochemistry 2

Subjects : dsst, science
  • 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. How protein synthesis is regulated prokaryoticly on plasmid of the cell

2. Is a code in which it is the same code forward as it is backwards - restriction sites

3. That doesn't contain a nucleus or membrane bound organelles (small cell)

4. Location of transcription

5. Lactose binds to repressor and it releases from operator

6. Bacteria cell that contains: CW - periplasmic space - & CM

7. Leading strand

8. Stains the Lipid A of gram positive bacteria cell wall

9. Spontaneous - doesn't require energy

10. Found the transforming factor to be DNA

11. Loss of e-

12. 'four'

13. Outermost layer of the Gram Positive bacterium

14. Break down of molecules

15. NAD+ and a hydrogen - e- carrier

16. A sequence of three nucleotide in DNA & RNA

17. How strong a molecule/atom can pull e-

18. Is an enzyme that cuts double-stranded or single stranded DNA at specific recognition sites

19. Has 2 layers CW - CM

21. Has 3 layers OM - CW - CM

22. Initiates transcription

23. Covalent bonds between amino acids

24. Found DNA to be the genetic material in cells

25. Bond between amino acids in a protein

26. The last - ending codon that terminates the sequence

27. Build up of molecules

28. 2 phosphates attached to glucose forming a 6 carbon compound & 2Pi (1 phosphate glucose) - ATP becomes ADP - done twice to make a 1 -6 glucose - phosphorolates and makes NAD+

29. It is the two single stranded regions of DNA that is being replicated

30. Series of amino acids held together by peptide bonds

31. Unzips the DNA double Helix

37. Messenger RNA that leaves the nucleus with the genetic code for a protein

38. Spiral

39. Process of using mRNA to create proteins

40. Replicated in fragments known as Okazaki Fragments

41. Glyceraldyhyde 3 Phosphaet Dehydrogenase - phosphorolates and reduces NAD by adding 2e- and a H+

42. Comma shaped

43. The chemical process in which glucose is broken down into two parts

44. Keeps the DNA strands separated

45. Acts as a mordant

46. Components of the CW linked by peptide bonds

47. Monomers of proteins

48. Coding regions on mRNA

49. Found the double helicle structure of DNA

50. 2 - 3 carbon molecules with 2 phosphates
