Therapeutic Cloning

Stem Cells

Found in multi-cellular organisms

Have the ability to divide (mitosis) and differentiate into various types of cells

Could be used to grow tissue to be used by humans

Transgenic Animals

Carries a gene from another organism

Usually implanted into stem cells

DNA Fingerprinting

Sorts DNA fragments by size

Used to compare DNA for crimes/forensic science and paternity tests
