Applications of
Genetic Engineering

Transgenic Organisms


Transgenic Organisms


contain genes from other organisms


These are produced by genetic engineering


Have helped bacteria produce things like insulin, growth
hormone, and clotting factors that were once very expensive


Allowed animals immune system to act more like humans which
allows them to study effects of disease


Can grow animals that are more lean

Cloning


Clone


member of a population of genetically identical cells
produced from a single cell



Bacteria can be cloned quite easily


In 1997, a Scottish scientist (Ian
Wilmut
) announced he had
cloned a sheep
-

Dolly

A donor cell is taken from
a sheep’s udder.

Donor
Nucleus

These two cells are
fused using an
electric shock
.

Fused Cell

The fused cell
begins dividing
normally.

Embryo

The embryo is placed
in the uterus of a
foster mother.

Foster
Mother

The embryo
develops
normally into a
lamb

Dolly

Cloned Lamb

Egg Cell

An egg cell is
taken from an
adult female
sheep.

The nucleus of the
egg cell is removed.

Carbon Copy Cat

Cc surprised many when she was born and did not look or
act exactly like the genetic mother

Human Cloning


In 2005 the UN approved a non
-
binding global ban on human
cloning


In US it is legal for non
-
embryonic stem cell research under
certain regulations
