and Genetic Engineering
researchers have investigated gene structure for many
years and know exactly the sequence of animal, plant, and
bacterial genes, and the regions which allow the
to be expressed. Genetic engineering allows one to
actually change the sequence of the DNA at these
important regions to allow a human gene for example to be
expressed by bacteria. One can get this gene into the
of a bacterium.
Then, this human gene will be expressed in a bacterium,
and a human protein can be made. This protein can then be
produced in great quantity, isolated, purified, and given
to people who need it.
