Genetics and Evolution

2 classes ago, we watched a video about DNA and Gene Technology and answered 20 questions in groups. Then students were given a DNA worksheet to complete as a bonus assignment.

Bonus assignments completed are to be handed in completed for extra marks. Answers need to be looked for in the biology textbook, in class notes and on the internet.

Today we did an experiment to isolate DNA from a banana and observe it in a solution in our testtubes and under a disecting microscope.

Homework: Study for the Genetics and Evolution TEST on Tuesday, Oct. 28
The test will include everything we've learned about Genetics and Evolution. We covered:

• Chapters 7 and 14 in the textbook
• additional information in our fill in the blank notes and other class notes
• DNA and RNA structure and function
• how DNA, RNA and proteins are made, including complementary base pairing
• the role of DNA in evolution
• 5 agents of evolution: genetic drift, mutation, gene flow, non-random mating, and natural selection
• knowing the difference between and giving examples of convergent and divergent evolution and speciation
• gradual and punctuated equilibrium models of evolution
