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=zlq. D 4 U WCuws
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=k 7 of. CWJi. Ug
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. .
