1. AP Biology DiscussionNotes Friday 01/16/2015

2. Goals for Today Be able to describe how restriction enzymes work and why they are valuable to scientists Be able to interpret a restriction map and predict restriction fragments produced by different restriction digests. Be able to describe how DNA extraction, gel electrophoresis, & PCR reactions work

3. Question of the Day 1/16 What is a restriction/recognition site?

4. Question of the Day 1/16 What is a restriction/recognition site? GAATTC

6. DNA Scissors Palindromes –Read the same 5’-3’ Base pairs must match (be complimentary)!

7. DNA Assignment Turn in IF 100% Complete DO NOT WORK ON THIS IN CLASS – the time has passed – need to work on our new assignments

8. Virtual Labs DNA Extraction Gel Electrophoresis PCR (Polymerase Chain Reactions)

9. Work Order Today Work on finishing DNA scissors Work on Biotech Virtual Labs –Take your time to READ carefully! –These topics will become fair game for a quiz! –ASK QUESTIONS

10. Planning Ahead… Monday -DNA Scissors DUE Friday – Quiz on DNA structure/replication & Names! Next Discussion: –Read through chapter 17 (page 122)

11. Species of the Day 1/16 Downy Woodpecker –Picoides pubescens

12. Species of the Day 1/16 Downy Woodpecker –Picoides pubescens

14. Species of the Day 1/16 Downy Woodpecker What enzyme is this woodpecker is responsible for unzipping the Double helix so replication can begin?
