:Technology based on biology

What is Biotechnology?

Biotechnology is grounded in the pure biological sciences of :

• genetics, • microbiology, • animal cell cultures,• molecular biology, • embryology and• cell biology.

• Harnesses cellular and bimolecular processes to develop technologies

Why biotechnology?

• Nature has a rich source of variation

But we know nature does not have

all of the traits we needBut nature does not contain all

thegenetic variation man desires

Solution

Biotechnology helps in

creating products that helps to

improve our lives and the health of

our planet

Application

• Examples

Medicine

Agriculture

Environment

Forestry

Food and beverage processing

• Created by inserting DNA from one organism into another

• OR modifying an organism’s DNA to attain a desirable trait.

Herman the Bull

Who is Herman the bull?• Herman the Bull, the world's

first farm animal carrying a human gene

• Herman, the transgenic bull who carries the human gene for lactoferrin.

How?

• Herman was genetically engineered in a laboratory at the early embryo stage. Scientists microinjected cells with the gene coding for lactoferrin.

• The scientists then cultured the cells in vitro to embryo stage and transferred them to recipient cattle.

Purpose?

• In the hope that milk produced by his female offspring would bear a human milk protein. 

What Happened?

On April 2, 2004  he died at the age of 13 because of Athritis.

GENETICALLY MODIFIED ORGANISMS (GMO)\

Is GMO aFriend or Foe?

Example Benefits of GMO

Higher yielding crops, more efficient use of land

Can save money and promote higher profits

Longer shelf life, less waste and stays fresh much longer.

Enhanced taste and quality

Reduced maturation time

Example Risks

Certain gene products may be allergens, thus causing harm to human health

There may be unintended harm to wildlife and beneficial insect

Risk for environment Promote animal abuseGene Transfer to non target

species
