How GE is done
Useful gene cut from one organisms chromosome using enzymes.
Enzyme's then used to cut another organism's to insert useful gene.
This produces genetically modified organisms.
Enzymes used to cut the DNA called Restriction Enzymes.
REDUCING VITAMIN A DEFICIENCY
Beta-carotene used in our bodies to produce vitamin A.
Golden rice - variety of GM rice.
Contains two genes from other organisms which enable rice to produce beta-carotene.
PRODUCING HUMAN INSULIN
Human insulin gene inserted into bacteria to produce insulin.
INCREASING CROP YIELD
GM crops have had genes modified (Make them resistant to herbicide)
Fields of crops sprayed with herbicide and all plants except GM crop killed.
