Changes

Work done by American geneticist [[Barbara McClintock]] showed that [[gene|genes]] could jump between DNA strands. Biologists can now transfer genes from one organism to another. For example, genes that stop deep-water fish from freezing in the [[Antarctic]] can now be put into a tomato, to make it resistant to frost.{{fact-science}}

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 stop 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>

Many people are worried that if people are ever designed genetically, the human race could change in ways we cannot foresee. Most countries still have laws to prevent scientists researching genetic engineering in humans.
