Here's a taster:

Genetic modification
micro organisms can be modified to produce a
useful product. For example an enzyme or a
drug.
Plants can be modified to make them resistant to
things like herbicides, frost and disease.…read more

Here's a taster:

The stages of genetic
modification
First the gene that is responsible for producing
the desirable characteristics is selected.
Its then cut from the DNA using restriction
enzymes, an isolated.
The useful gene is often jointed to a vector a
carrier for the gene which makes it easier to
insert into a new cell. The gen is inserted into
the vector using the enzyme ligase. Plasmids
are often used as vectors.…read more

Here's a taster:

The stages of genetic
modification
The useful gene is inserted into the host DNA
of the organism (usually using a vector)
This produces an organism with the desired
characteristics.…read more

Here's a taster:

Genetically modified organisms can
be used to make insulin...
The gene for human insulin production has
been put into bacteria. These are cultured in a
fermenter, and the human insulin is simply
extracted as the produce it. There are
advantages and disadvantages of making
drugs and hormones. (next slide)…read more
