1. Assignment 3 Inheritance Assignment 4 Genetic Modification
Unit 18
Assignment 3 Inheritance
Assignment 4 Genetic Modification

2. Lesson Objectives
Go over Assignment 3 again to check progress and answer any questions.
Begin Genetic Modification
Workshop to be used for planning / writing up assignment or researching genetic modification.

3. Assignment 3 Pass = Genetic Crosses
Merit = Write up of Fruit Fly practical
Distinction = Chi Squared analysis

4. Distinction You will need: Set of pooled results
Chi squared help sheet
(do not just hand this in, it needs to be written up in your own words)
Data table

5. These are the Observed results

6. Genetic Modification
Write down a use for genetic modification / genetic engineering on a post-it note.
Stick the post-it to the board:

7. Assignment 4/5
Your next assignment will require you to understand the processes involved in working with DNA in the laboratory, including genetic engineering.
Assignment 5 will require you to research and present to the class information about genetic modification.

8. GM- The basics:
Genes can be ‘’cut’’ out of a DNA strand using enzymes.
What are those enzymes called?
Restriction Endonucleases
Microbes such as Bacteria are routinely used in genetic engineering. Why?

9. Restriction Endonuclease Action:

10. Some uses of GM: Manufacture insulin Frost resistant crops
Pest resistant crops
Gene therapy (in medicine)

11. Crash Course

12. Problems! Genetic Engineering is still very controversial. Why?
Discuss with somebody sitting near you the reasons that people might not like the idea of modifying genes.
Write down at least 3 things you discussed
Write one of these on the board.

13. Human GM:

14. Class Work For the rest of today’s lesson you can:
Plan & write out by hand any remaining tasks on Assignment 3 (inheritance) including the Chi squared analysis.
Research and make notes on GM. Uses, methods used, ethics involved etc..
