Lesson #10:
Cloning
Learning Intention:
Students will be able to explain the process of cloning and discuss its applications and implications, drawing upon concepts of genetics and biotechnology
Success Criteria:
I am successful when I can...
Discuss potential applications of cloning, such as bringing back extinct species using genetic editing techniques like CRISPR cas 9.
Identify and discuss ethical and moral dilemmas associated with human reproductive cloning, such as questions of individuality and the potential for misuse
Use relevant tier 3 vocabulary (such as fertilized egg, womb, genetically identical, DNA, genes, chromosomes) when explaining cloning concepts
Explain some of the scientific challenges that currently prevent widespread human cloning
Reminders:
EOU genetics exam tomorrow!
Standards
HS-LS3-2. Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, (3) mutations caused by environmental factors and/or (4) genetic engineering

Part 5:
Take-Away
Somatic Cell Nuclear Transfer (SCNT): is a laboratory technique used to create a viable embryo (a clone) by taking DNA from a body cell (somatic cell) and inserting it into a donors egg cell.
Part 6:
Rapid Writing
Directions:
1) View the image below.
2) Write NON-STOP for two minutes about anything related to the image or our genetics unit.
3) If you can't think of anything to write, just write anything at all.
Part 7:
S.I.T
Why haven't we cloned humans yet?
