List five things that come to
mind when you think of
biotechnology.

Objective

It is expected that the learner will:


1.
Build strong content knowledge
about biotechnology.


B
IOTECHNOLOGY

Biotechnology


The use of gene science to
create new products from plants
and animals

History


Biotechnology has been around before
we had science


Yeast to make bread rise


Bacteria to ferment sauerkraut


Bacteria to produce cheese, yogurt


Transform grain into alcohol

Biotechnology


Silage


Used for animal feed


Green grasses and
grains stored in air
tight containers


Converts sugars and
starches to acids

Biotechnology


Silage


Silage is made
either by placing cut
green vegetation in
a
silo
, by piling it in
a large heap
covered with plastic
sheet, or by
wrapping large
bales in plastic film.

The Genetic Connection


Genetics


Biology of heredity


Transmission of
characteristics from an
organism to its
offspring through
genes in reproductive
cells


Gregor

Mendel


Experimented with
garden pea plants

The Genetic Connection


Genes


Components of
cells that determine
individual
characteristics of all
living things


Comprised of DNA


The “Blueprint” of
cells and their
successive cells

The Genetic Connection


Gene
Mapping


Matching a gene to a
trait


Determines what gene
is responsible for
certain traits


Could not be done
without high speed
computers

Application of Biotechnology


DNA Matching


Identifying the parents of
offspring


Genetic engineering


Early 1980’s


Modifies the genetic make
-
up of animals and plants


Movement of genetic
information (genes) from one
cell to another

Products of Genetic
Engineering


Insulin


Treats diabetes


Herbicide resistant
crops


BST (bovine
somatotrapin
)


Increases milk production


Lee
-
minus


Bacteria that retards frost
formation on plants


Convert waste to fuel

The American Society for Microbiology


“…plant varieties created with biotechnology
are grown more efficiently and economically
than traditional crops. This eventually should
result in a more nutritious product at less
cost to the consumer as well as reduced
pesticide use and greater environmental
protection.”

Dr. Patrick Moore

Environmental Consultant

Co
-
Founder of Greenpeace

“The campaign of fear now being

waged against genetic modification is

based largely on fantasy and complete

lack of respect for science and logic.”

23.

Norman Borlaug, Ph.D.

Professor, Texas A&M University

Nobel Peace Prize Laureate, 1970



“I believe the world will be able to produce
the food needed to feed the projected
population of about 8.3 billion in the year
2025…but it cannot be attained without
permitting the use of technologies now
available or without research to further
improve and utilize new technologies,
including biotechnology and recombinant
DNA.”

Michael Jacobson

Executive Director

Center for Science in the Public Interest


“While biotechnology is not a panacea for
every nutritional and agricultural problem,
it is a powerful tool to increase food
production, protect the environment,
improve the healthfulness of foods, and
produce valuable pharmaceuticals. It
should not be rejected…”
