Transcript of Genetic Engineering and Stem Cells. * Restriction enzymes: * Have sticky ends or overhangs of DNA. *...
- Slide 1
- Genetic Engineering and Stem Cells
- Slide 2
- * Restriction enzymes: * Have sticky ends or overhangs of DNA. * This helps to glue in the gene of interest in the right direction. * Must find a plasmid with the appropriate sticky ends that match your gene.

- * Learn how a mouse is cloned. * http://learn.genetics.utah.edu/content/cloning/ clickandclone/ http://learn.genetics.utah.edu/content/cloning/ clickandclone/ * Many copies of identical mice are cloned from mouse embryos. You can have essentially 1000 identical twins with the same genetics. * This has been used in science for many years.

- * Epigenetic patterns already in place (how is DNA tagged to turn genes on and off?) * Transplantation process is costly. * Cells are genetically older. Telomerase has been deactivated.
