What is Biotechnology?


Biotechnology is any technique that
uses living organisms (or parts of
organisms) to make or modify
products, to improve plants or
animals, or to develop
microorganisms for specific use"

Biotechnology


Traditional biotechnology was
brewing beer and wine or making
bread or cheese.


The new biotechnology has been
improving society in profound ways
with new medicines, foods,
fertilizers, and a wide range of
processes.

Uses of Biotechnology


May be used to monitor the health of
the environment with biosensors.


Cleans pollution by degrading
complex chemicals into simpler
substances.


Helps crops become resistant to
insects and pests without the use of
as much pesticide.

Ethics


However, biotechnology has also
caused society to examine its values
by implementation of technologies
like:


"designer babies,"


replacement limbs


organs grown from stem cells



biological warfare agents



the artificial extension of life by slowing
the aging process.

Biotechnology Areas

Environmental Applications


Bioremediation is using organisms in
processes that help to clean polluted
environments.

Biotechnology Areas


Agriculture and Biotechnology


Genetically altered crops and animals
are among the most significant
applications of biotechnology.

Genetic
engineering has enabled both crop and
livestock producers to create
improvements to stocks.

Biotechnology Areas


Bioprocessing


Biological organisms are also important
in the production of products in
industry.


Bacteria are especially useful in
purification and separation processes.



For example, one particular type of
bacteria is being used in the mining and
refining of gold.

Biotechnology Areas

Genetic Engineering :


Genetic engineering is based on the manipulation of genes. If
there were two organisms, say bacteria, and each had
different but desirable characteristics, then the genes
responsible for each characteristic could be combined in one
of the organisms.


Aquaponics and aquaculture assisted in the
development of hardier stocks of fish and crops by using
genetic engineering.


Used to produce a more human
-
like insulin.


Has aided in the development of vaccines.


DNA, the genetic makeup of all life forms, is the key to
genetic engineering success.


Cloning is an example of genetic engineering.
