Changes

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>
