: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
