What is Genetic Engineering?
Genetic
engineering is a relatively new branch of science, often misleadingly
called the new biotechnologies in an attempt to liken it to the
centuries-old industrial use of biological processes, as in bread-making
and beer brewing.
The term
'biotechnology' refers to the science of using living organisms,
for example, the use of yeast cells to make bread and wine. The
term is also used to describe the careful breeding of plants or
animals to produce a particular, desired result. Traditional biotechnologies
have given us hothouse roses with unique colouring and cows with
higher meat or milk yields. Genetic engineering, on the other hand,
involves taking genes out of an organism's cells and altering them
in some way. It enables scientists to transfer genes between different
species to produce genetically engineered organisms (GEOs) with
new characteristics.
Genetic
engineering has been seized upon by scientists and industry as a
way redesigning and 'improving' living organisms. Genetic engineering
in agriculture focuses on conferring new properties on commercial
crops, like herbicide resistance, nutritional change, insect resistance
or stress tolerance. Industry claims that these 'improvements' will
increase efficiency and productivity. In fact, their main motive
is increased profits.
