1. AP Biology Discussion Notes Tuesday 02/03/2015

2. Goals for Today NEED YOUR CHROMEBOOKS TODAY Be able to describe the possible affects and different types of mutations Be able to decode the message in messenger RNA (mRNA) Be able to list the molecules & structures involved in Transcription & Translation.

3. Question of the Day 2/3 Go on to our website and answer the following question, Do YOUR best, and do not discuss this with your neighbors.

4. 1.DNA nucleotide base #2 is cytosine. The RNA base of #6 is: A.Adenine B.Cytosine C.Guanine D.Thymine E.Uracil

5. 1.DNA nucleotide base #2 is cytosine. The RNA base of #6 is: A.Adenine B.Cytosine C.Guanine D.Thymine E.Uracil

6. Mutations Thinking Harmful Helpful Neutral Let’s think of DNA as a recipe (which it is) But maybe for something like chocolate chip cookies.

7. Mutations Thinking Needed that exact protein, and not it is not that exact protein Take out chocolate chips Take out a unit Switch chocolate chips for anchovies Take out temperature or baking at all.

8. Mutations Thinking What kind of mutation would be neutral (have “no” effect) Other less important areas of DNA that don’t code for anything Maybe you delete a space or a spacing line.

9. Mutations Thinking Maybe you add something that will help that protein do an even better job Maybe you add M&M’s or More chocolate chips

10. How would a mutation become permanent?

11. Is there a mistake here?

12. Can you tell which one is the mistake? Could a non- thinking enzyme tell which one is the mistake?

13. When do Mutations become problems…. How about a mutation in a cancer/tumor suppression gene?

14. Work Order Today 1.Turn in Friday’s Mutation activity (if you didn’t yesterday) 2.Finish the exploring mutations online –DUE TOMORROW 3.Begin Reading Guide (331-336) 4.Work on Extra Credit

16. Species of the Day 2/3 Eastern Screech Owl –Megascops asio

17. Species of the Day 2/3 Eastern Screech Owl –Megascops asio

18. Species of the Day 2/3 Eastern Screech Owl –Megascops asio Why is mutation important in evolution?
