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

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.

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

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

These are the Observed results

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

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.

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? https://www.youtube.com/watch?v=zlqD4UWCuws

Restriction Endonuclease Action:

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

Crash Course https://www.youtube.com/watch?v=k7-ofCWJiUg

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.

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..
