How is Genetically
Modified Bacteria made?
A small piece of circular
DNA called a plasmid? is
extracted from the
bacteria or yeast cell. A
small section is then cut
out of the circular
plasmid by restriction
enzymes, 'molecular
scissors'. The gene for
human insulin is
inserted into the gap in
the plasmid. This
plasmid is now
genetically modified.
