Changing an organisms genes to alter its characteristics
How have GM crops had their genes genetically modified?
Make them resistant to viruses, insects or herbicides
What are herbicides?
Chemicals used to kill weeds
How have sheep been genetically engineered?

Has potential to solve problems such as diseases
Worries of long term effects
How is genetic engineering done?
Useful gene cut from chromosome using enzymes
Enzymes cut another chromosome so there is space for the useful one
Useful gene inserted
