Werid Science
Ancient Biotech
Begins
with early civilization
Developments in Agriculture
and food production
Few records exist
Cheese
 One
of the first food products
made through biotechnology
 Began
some 4,000 years ago
 Nomadic
tribes in Asia
Cheese
 Strains
of bacteria were added
to milk
 Caused acid to form
 Resulting in sour milk
Cheese
 Enzyme
called “rennet” was
added
 Rennet comes from the lining
of the stomachs of calves
Rennet is now genetically
engineered
Yeast
 Long
used in food preparation and
preservation
 Bread
 Yeast
baking
produces a gas in the dough
causing the dough to rise
Yeast and
Fermentation
 Fermentation
 Process
in which yeast enzymes
chemically change compounds
into alcohol
 In making vinegar the first product
of fermentation is alcohol
Antibiotics
 Penicillin
 Developed
in the late1920’s
 Introduced in the 1940’s
 First drug produced by
microbes
Modern
Biotechnology
Cloning- Plants and animals
 Disease and Pest resistance in plants
 Genealogy- where did we come from?
 MedicineGene therapy, Genetic testing,
Medications- what will work best for
you

Modern
Biotechnology



Evolution studies- compare genomes
Humans/chimpanzees
Humans/yeast
Whales/cows
GMO- Genetically Modified Organisms
Bacteria/Plants/Animals/
Humans?
DNA Testing- what are you at risk for?
what traits might you have?
Modern
Biotechnology

Genetic Engineering of Proteins
- HGH, EPO, Insulin, Clotting factor,
many, many, many food additives
- Medications- almost all disorders stem
from altered protein function
- Vaccine production and delivery
The Default Answer is Always
!!! PROTEINS !!!
