'''Genetic Engineering''' is the deliberate manipulation of an [[organism']]s [[genetic]] material.

Work done by American geneticist Barbara McClintock showed that [[gene|genes]] could jump between DNA strands. Biologists can now transfer genetic information from one organism to another. For example, genes that produce a protein that stops deep-water fish from freezing in the [[Antarctic]] can now be put into transgenic tomatoes, potatoes, and tobacco, to make them more resistant to frost.<ref>http://www.biobasics.gc.ca/english/View.asp?x=795</ref>

Some people believe that modifying food crops to improve the [[vitamin content]] or make them resist [[drought]] or herbicides will provide the world with more and better food.

Genetically engineered [[bacteria]] can produce human [[insulin]] for [[diabetes|diabetics]]. Scientists hope they will be able to use it in the future to cure DNA errors that cause illnesses such as [[muscular dystrophy]] and [[cystic fibrosis]]. Cures though, are not yet imminent.
