1. Genetic Engineering – Ch. 13

2. Selective Breeding  Used by humans to pass desired traits from one generation to the next  Animals with desired traits breed  Domestic animals  Inbreeding – continued breeding of individuals with similar characteristics to keep lines “pure”  Plants  Hybridization – cross dissimilar individuals to bring together best of both worlds

3. DNA Fingerprinting  Analyze sections of DNA that have little or no known function  Sections that vary widely from one individual to another  Positive ID has similar marker to mother AND father  Remember you get your chromosomes from both your mom AND your dad

4.  Uses gel electrophoresis – gel setup between two poles; positive charge on one end and negative on the other  Amino acids have different charges and travel along the gel depending on that charge  Figure 14-18: which suspect matches the evidence?

7. Cloning – Ch. 13  Donor cell taken from original animal  Fused with egg cell with no nucleus  Fused with electric shock  Dolly  First mammal cloned  Offspring genetically IDENTICAL to parent/donor

9.  CC (Carbon Copy): Cat that was cloned  http://www.msnbc.msn.com/id/30769 08/ http://www.msnbc.msn.com/id/30769 08/ http://www.msnbc.msn.com/id/30769 08/

10. Human Genome Project  Scientists working on full set of chromosomes/DNA sequence of humans  Look at haploid set of chromosomes  Human genome - ~3 billion base pairs

11. Stem Cells  Unspecialized cells with the potential to become a variety of cells  Taken from embryos or umbilical cord  Moral and ethical objections  Immune system may reject stem cells  Mouse cells used to date

12.   In 2009 President Obama lifted the ban on embryonic Stem Cell research placed by the Bush Administration.   http://school.nettrekker.com/goExternal?np=/ext ernal.ftl&pp=/error.ftl&evlCode=272773&produc tName=school&HOMEPAGE=H http://school.nettrekker.com/goExternal?np=/ext ernal.ftl&pp=/error.ftl&evlCode=272773&produc tName=school&HOMEPAGE=H   What do you think? On a separate sheet of paper, put your name and the date. Choose a side. Pro Stem Cell research or Anti Stem Cell research? Defend your argument with examples.
