Genetic Manipulation

The New You of Tomorrow






By: Vincent Zhu

What is Gene Manipulation?


Gene manipulation is as it is called, the
manipulation of genes,


the transformation of genes


cutting and joining of DNA


research

History of Gene Manipulation


1869
-
Friedrich Miescher discovers the
existence of DNA


1970s
-

scientists proposed what they
called "gene surgery" for treating
inherited diseases caused by defective
genes.


1978
-
Hamilton O. Smith, Daniel Nathans
and Werner Arber

discover how to cut
apart lines of
DNa



History of Gene Manipulation


1988 launch of the human genome
project


1996 First mammal cloned, the Sheep
Dolly


1997 Rice Tec given Patent on Basmati
Rice


2000, President Clinton announced that
the genome sequence could not be
patented

Fields of Gen manipulation


Gene Splicing


Cloning


Genetic therapy and Medicine


Direct genetic engineering

Gene Splicing


Gene

splicing

allows

scientists

to

identify

specific

genes,

remove

them,

and

duplicate

them

and

use

them

in

another

part

of

the

same

or

in

an

entirely

different

organism
.



The

use

of

this

innovation

has

broken

the

barriers

between

species

and

allowed

further

evolution

of

agriculture

and

animals
.

For

example

crops

that

endure

cold

and

has

it

own

natural

pesticide



Cloning


The process of creating a completely
genetically identical individual to the
original.


This process has great potential help the
world in creating stem cells, organs or
possible recreate lost animal species


Such ideas have been express greatly in
fictional movies like Star Wars and the Sleeper

Medicine


Through Genetic therapy, curing disease
such as cancer, leukemia, and other
genetically passed down diseases are now
possible.


Pharmacogenomics has created medicine
to control our moods such as Ritalin;
through this process drugs are better,
safer, and more personalized for you

Direct Genetic Engineering


Direct gene manipulation

can manipulate
your genes right from birth to prevent future
defects and give better physical assets. We can
use embryo screening, which done commonly
today, to screen the embryo for genes that
cause heritable diseases, physical defects,
depression. Parents are allowed the choice to
either keep or discard the embryo and can even
change the DNA chains and replace the
unwanted one with better ones.


Pros


Better medicine


More nutrient efficient foods


Longer life expectancies


No more genetically passed down
diseases


Unlimited potential


Better Health

Cons & Controversies


Morally and ethically incorrect


Lost of identity in society


Social inequality


Renewed biological warfare


Still very experimental

Cons


Gene Patenting has
pushed farmers out
of the farming
business forbidding
them to grow their
crops

Why shouldn’t we ignore This


There are many helpful solutions that
come form genetic manipulation


Stem cell research


Medicine


Cure to genetic diseases


It isn’t the burden of scientist to control
and regulate what can be done, its Society
and Government.


This technology is still experimental
because public option is holding it back

Why should we



people are already de
-
evolving with high
dependence on other technologies leading
to obesity and un healthy practices


People are not going to evolve on their own
because society rejects such differences


The possibilities within genes are unlimited


This process is already a possible event and
if we don’t take some interest in it now it
will be reserved for the rich and powerful


It is human to evolve


The End
