1. Stem Cells and Cloning

2. Stem Cells
Stem Cell: a cell that can continuously divide and differentiate into various tissues
Two Types:
Multipotent: adult stem cells and somatic cells
Pluripotent: embryonic cells and induced pluripotent stem (iPS) cells

3. Cloning
Clone: an organism, cell, or piece of genetic material that is identical to the one that was preexisting; to make a genetic duplicate
Natural cloning: asexual reproduction
Abnormal development is the reason most clones do not survive very long

4. SCNT: Somatic Cell Nuclear Transfer
Remove nucleus of surrogate’s egg cell
Replace with nucleus of adult cell you wish to clone:
Place cell next to empty surrogate egg cell
Use an electric shock to open membranes and fuse cells
Cell will begin to divide and develop into an embryo – implant into surrogate

8. Cloning Humans?
Is it possible? Is it something we should be worried about?

10. Essay Question
You and your spouse are ready to have a child, and the doctor presents you with the option of genetically engineering your baby. Based on what you learned today, would you like to genetically engineer your child or have a natural birth? Include why you made the choice you did.
