1 Title: Biology 3/2/07 Objectives: Class Topics
11/29/2018 Title: Biology 3/2/07 Objectives: To assess learning about Chapter 8. Class Topics Hand in “Natural Selection and Allele Frequency lab” before the bell rings Review Chapter 8 Quiz 3 Chapter 8 Test Inbreeding article Notes – Chapter 9 “Failure is only postponed success as long as courage “coaches” ambition. The habit of persistence is the habit of victory.” Herbert Kaufman Thursday, November 29, :23 PM

2 Class Assignments Chapter 8 Test 3/2/07
11/29/2018 Class Assignments What By When Chapter 8 Test 3/2/07 Lab – Natural Selection and Allele Frequency 3/2/07 Read /7/07 Due this class period Due next class period Due in the future

3 11/29/2018 Grade Sheet 2A – p. 157 (5 pts.)

4 Posttest Activities Hand in the test
11/29/2018 Posttest Activities Hand in the test Pick up the article “Go Ahead and Kiss Your Cousin” Read the article Please do not write on this Review the questions on the following slide

5 Review Magazine article “Go ahead and kiss your cousin”
11/29/2018 Review Magazine article “Go ahead and kiss your cousin” Why are neural degenerative diseases 8 times more common in Bradford than the rest of the UK? (62) What are lethal alleles (62)? Why is it likely that 80% of marriages in history were between 2nd cousins or closer? (62) Why would some rich families encourage cousin marriages? (63) Why do some cases of inbreeding lead to many diseases while others do not? (63) What is outbreeding? (64) What are some problems with outbreeding? (64)

6 Johann Friedrich Miescher
11/29/2018 first scientist to isolate DNA Studied pus from wounds Called DNA - nuclein Accomplishment not acknowledged at the time Johann Friedrich Miescher

7 Frederick Griffith working on vaccine for pneumonia (1928) Strains

10 11/29/2018 Transformation Something changed the IIR strain to the IIIS strain. What was it? Transformation is the process of changing one form of bacteria into another form trading genetic information Between dead (HKIIIS) and living IIR

11 Historical Perspective
11/29/2018 Historical Perspective Genetic material Believed to be protein More complex than nucleic acids More common than nucleic acids

12 Avery and Co. McCarty & MacLeod
11/29/2018 Avery and Co. McCarty & MacLeod took Griffith’s experiment one step farther found out what had caused transformation Used enzymes to breakdown organic molecules - Carbohydrase, Protease, Ribonuclease, and Deoxyribonuclease
