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.

21. Has enough energy to created the peptide bond






22. 9+2 arrangement of microtubules -






23. Different exons can be combined to make nique protiens in different times






24. Microvilli - muscle contraction - cytokinesis - adhering juntions






25. 1P (blocked by tetracycline)
