During the DNA extraction, the strawberry was treated with a extraction buffer the material was filtered through a coffee filter.

7. How did the extraction buffer work? (Why were the chromosomes liberated from the cells of the strawberry?)

8. What was the purpose of the coffee filter?

9. Is the DNA found in all living cells (bacteria, plants, animals, etc.)?

10. The molecule above is what form of nucleic acid?

11. The molecule above is what form of nucleic acid?

12. The model above represents the relationship between RNAs and DNA. What is Process "1" called ________________________

13. What is process "2" called ________________

14. What RNA is involved in coping the information from DNA and take it out to the cytoplasm? _________________________

15. What are the small RNAs that grab an amino acid to be joined together? ______________________________

16. On what organelle does all of this take place? ____________________________

Note the mRNA codes conversion table above: The control codes (Start and Stop) do not code for an amino acid. except for AUG, when it appears after an initial AUG and before a Stop code.

17. What three letter code means start here?___________

18. What are the three letter codes which means stop?

19. Write the DNA base pairings above.

20. Write the mRNA pairs above.

21. How many of the codes (not sets) from above (21 codes) are actually used to code for an amino acid? ___________

22. How many of the codes from above (21 codes) are used to control the process (start and stop)? ________
