Transcript Cloning or Genetic Modification

CLONING OR GENETIC
MODIFICATION
What’s the difference?
In the novel Jurassic Park
by Michael Crichton:
• Scientists used ancient
dinosaur DNA trapped in
amber to clone extinct
species.
• They designed a theme
park around this idea to
earn profits on tourism.
• The cloned dinosaurs
eventually became
uncontrollable and the
scientists abandoned
their project, sacrificing
many lives along with
their investment.

What’s Your Opinion?
• Do you think there was
anything the scientists
could have done to
reduce the risk?
• Is there any way to
bring extinct organisms
back by any other
means?

Many organisms have been cloned in the
past 50 years with varying success
• Mice, cattle, sheep,
cat, deer, dog, horse,
mule, ox, rabbit and
rat, and a rhesus
monkey have all been
cloned.
• Some lived longer than
others.
• Dolly the sheep
(cloned in 1996) only
lived about 6 years.

Cloning vs. Genetic Modification
Cloning humans is
currently not allowed by
law in any country on
Earth.
Genetic modification is
currently used to
replace or repair
mutated genes or to
add new traits to an
organism.
Genetic Modification
• defined as changing the genes of an organism using
Biotechnology.
• usually involves one gene, or a few genes, that contain
instructions for a specific trait.
• this has an effect on the resulting trait in the organism.
• can be used to replace or repair existing genes, or
introduce brand new genes for new traits.
Genetically Modified Organisms
Some modified traits are
easily visible like
these glowing animals.

And some modified traits are not easy
to see, such as the disease resistance
introduced to these fruits and
vegetables
