2. Biotechnology
Definition of biotechnology: "...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"
(Wells, Poszywak, & Dunham, 2000,
p. 63).
3. Biotechnology
However, biotechnology has also
caused society to examine its values
by expanding toward the
implementation of technologies like
"designer babies," replacement
limbs and organs grown from stem
cells, biological warfare agents, and
the artificial extension of life by
slowing the aging process.
6. Biotechnology Areas
Environmental Applications
Bioremediation is using organisms in
processes that help to clean
polluted environments. Biological
controls, biosensors, biotreatment,
biorestoration, and
phytoremediation are all means of
using biotechnology to clean or
protect the environment.
8. 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 and implement them in one or
two generations.
9. Agriculture and Biotechnology
We already eat
genetically altered
vegetables such as
tomatoes
Hairless Chicken will save
money by decreasing the
time and tools used to
pluck the hairs off chickens
10. 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.
12. Genetic Engineering
Genetic engineering is based on the
manipulation of genes (Grace, 1997).
Genes hold the blueprint for how every
living thing grows, looks, and behaves. 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.
