Start of Genetic Engineering
Genetic engineering: Scientific alteration of DNA.
Started after the discovery of DNA by James Watson and Francis Crick.
DNA determines physical and mental characteristics.
Types of Genetic Engineering
Germline Gene TherapyAlteration of genome takes place in reproductive cell.
Alterations can be inherited if inserted into chromosomes.
Mostly done in animals.
Types of Genetic Engineering
Somatic Cell Gene Therapy
Alteration of genome in other than sex cell.
Bad genes can be swapped for good ones.
Not inheritable.
Limited success rate.
THE DOWN SIDE
Creating bigger salmon..
May feed more people..
But is it right?
Chicken with no feathers.
Would you eat this?
You wouldn’t know if you were.
Is this right?
COMPANY
CONTROL
BUT DOES IT HAVE BENEFITS?

More People = More Food
Crops are engineered to resist disease.
No disease means more crops last.
More crops means more food for the growing population.
Advancements bacteria producing insulin mice producing human heart attack drugs
in their milk goats who carry cancer fighting protein in
their milk sheep with a blood clotting aide in their milk a hen who produces a cancer fighting agent
in her eggs a bull was cloned that was resistant to
brucellosis, tuberculosis, and salmonellosis
WHAT WILL HAPPEN?
WHO KNOWS?
