        Genetic Engineering and Working with DNA

        The technique illustrated in this animation produced by WGBH and Digizyme, Inc., shows how scientists use natural processes and technological innovations to insert genes into loops of DNA called plasmids. Plasmids can then be introduced into bacterial or other cells, which will proceed to replicate the inserted genes or induce the cells to produce such valuable proteins as human insulin and growth hormone. This resource is part of the Biotechnology collection.

        Genetic Engineering and Working with DNA

        Using genetic engineering, scientists can create cells that produce proteins they wouldn't ordinarily produce.
