What Is Biotechnology?


Any technique that uses living
organisms or substances from those
organisms to make or modify a product,
to improve plants or animals, or to
develop microorganisms for specific
uses


Biotech Terms


Genetics




the biology of heredity


Heredity




the transmission of characteristics from an



organism to its offspring through genes in



reproductive cells.


Genes




components of cells which determine the individual


characteristics of living things


Generation


refers to offspring of common parents


Progeny



offspring


Deoxyribonucleic Acid (DNA)



coded information in a cell that


determines what that cell and its successive cells



will be become.

Biotech Terms cont.


Clone




exact duplicate of something


Genetic engineering



movement of genetic





information in the form of genes from



one cell to another.


Mapping / Gene Mapping



identifying and recording


the location of a specific gene on a



chromosome.


Gene Splicing / Recombinant DNA Technology






process of removing and inserting genes


into DNA.

Historic Biotech Applications


Yeast


make bread rise


Bacteria


ferment sauerkraut






produce cheese(s)






other dairy products




Microorganisms


transform fruit and

grains into





alcoholic beverages


Historic Biotech Applications


Silage


green grasses and grains have been stored in air
-
tight
spaces and containers, such as silos, where bacteria convert
sugars and starches in acids.


These acids provide a desirable taste and protect the feed
from spoilage by other microorganisms

Double Helix

Create Duplicate Strands
