Uses of Genetic Engineering
With genetic engineering I can
produce milk that contains:
Lower levels of cholesterol
I am called a “transgenic”
ENZYMES “cut out” the part of
the human chromosome that is
responsible for producing insulin.
Using another restriction
enzyme cut open a ring of bacterial
DNA (a “plasmid”). Other enzymes
are then used to insert the piece of
human DNA into the plasmid.
Place the plasmid into a bacterium
which will start to divide rapidly. As it
divides it will replicate the plasmid and
make millions of them, each with the
instruction to produce insulin. Commercial
quantities of insulin can then be produced.
