What is Biotechnology?
General Definition
The application of technology to improve
a biological organism
Detailed Definition
The application of the technology to modify the
biological function of an organism by adding genes
from another organism
A wide ranging scientific field which includes the manipulation
of living organisms that results in new products or processes by
that cell.
Gregor Johann Mendel
Discovered the Laws Governing
the Genetic Inheritance of Traits
by Scientific Experimentation.
Founded Modern Genetics.
Gene - a piece of DNA that controls the
expression of a trait
Allele - the alternate forms of a gene
Genetic Engineering
The process of making changes in the DNA code of
living organisms
But nature does not contain all the
genetic variation man desires
•Fruits with vaccines
•Grains with improved nutrition

Products
Clothing (Spider Silk)
 Elastic, light weight fiber 5 times stronger than steel
 One method involves inserting the gene from a
weaving spider into a fertilized goat egg. The
resultant “spider-goat” produces milk that can be
manufactured into strong fibers.
Spider Silk
 To make flak jackets,
rope, textiles, sutures,
artificial tendons, and
bandages for burn
victims
Synthetic biology
Creating lifelike characteristics
through the use of chemicals
Based on creating structures
similar to those found in living
organisms
Molecular Biotechnology
Changing the genetic make-up of an organism
Altering the structure and parts of cells
Uses genetic engineering, molecular mapping and
similar processes
 Medicine
 Agriculture
 Environment
 Forestry
 Food and beverage processing
Medicine
Some new developments delve into the
hereditary material of humans known as gene
therapy
Therapeutant - product used to maintain
health or prevent disease
Biopharmaceuticals – drug or vaccine
developed through Biotechnology
Called designer drugs
Environmental
Problems naturally solved by
microorganisms such as bacteria,
fungi break down contaminant into a
form less harmful or not harmful
Plant Biotechnology
Improve plants and the products
produced from them
Insect and disease resistance
Engineered to have desired
characteristics
Animal Biotechnology
Improve animals or the
products they produce
Animals may be used to
produce products that promote
human health
Food and Beverages
Use of technology in producing
and processing
Some Biotechnology principles
have been employed for hundreds
of years
Yeast in baking bread
Efficiency
Must keep the cost of improving products as low as
possible
Biotechnology results in greater efficiency
Results in trees that grow faster and produce wood
that is more desirable
Biotechnology
Biotechnology helps to meet our basic needs.
Food, clothing, shelter, health and safety
Used to make products more useful or
desirable………..
