Genes and Cloning

There is a lot of controversy around genetic modification of organisms and cloning. This program looks at the way man has modified genomes of plants and animals used for food since the dawn of agriculture. As knowledge of cells and genetics has increased so has man's ability to alter genomes. Animations show how genetic engineers are now able to construct and insert genes for desirable characteristics into plants and how technology is used to increase numbers of animals with desirable traits and screen out those with disease or lower food yields.
