GENETIC ENGINEERING
Genetic Engineering
 Direct manipulation of an organism’s genes
Cloning
Cloning
 Different types
 Reproductive Cloning
 Used to create animals
that have the same
nuclear DNA as a current
or existing animal
Dolly

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
