DSST Biochemistry 2

Subjects : dsst, science
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. Protein that makes RNA primers and makes mRNA from DNA

12. Cuts the introns out of mRNA






13. Keeps the DNA strands separated






14. Many amino acids bonded together with peptide bonds






15. 2-layer permeable membrane that forms a continuous barrier around a cell
