IB Topic Presentation
Morgan Kaplan and Hubza Syeda

2. Overview Definition Types
“A group of genetically identical organisms or a group of genetically identical cells derived from a single parent cell”*
Types
Plant Cloning
Animal Cloning
Therapeutic
Reproductive
*Definition from IB Study Guide

3. Plant Cloning Plants have been cloned naturally for hundreds of years
Ex. Strawberries and runner stems
Cloning plants through vegetative propagation
Tissue Culture Propagation
Take piece of specialized root
Break them up into root cells
Leave cells in culture until dedifferentiation
Stimulate calluses (unspecialized cells) to grow with hormones

4. Therapeutic Cloning
Used to regenerate tissues, organs, or cells of organism
Process
Remove specialized cell (targeted body part)
Eggs from new donor are taken and nuclei are removed
Cells combined
Induced growth
New cells are inserted

5. The Therapeutic Cloning Debate
For
Against
Embryos have no nerve cells and cannot feel pain
Can be used for regenerative therapies that save lives
Can be removed from underdeveloped embryos that would die anyway
Reduced risk of transplant rejection
Every human embryo has a chance of life and should have the opportunity to develop
More embryos produced than will be used so some will have to be discarded
These pluripotent cells can become tumor cells
Used embryo does not develop

6. Animal Reproductive Cloning
Somatic cell nucleus transfer (SCNT)
Similar to therapeutic cloning
Banned in many states and countries
Embryo implanted into uterus (surrogate mother)

7. Dolly
