Genes can be Moved Betweeen Species

This is a chapter of the larger site "DNA from the beginning". This section discusses the discovery of mechanisms by which bacteria can naturally transfer DNA in the form of plasmids, called transformation. It then describes how this discovery was used to develop recombinant dna techniques to insert specific DNA sequences and select for them using antibiotic and provides the example of creating insulin through recombinant methods. The material is taught by explaining the experiments that resulted in our understanding of this subject. For all of the modules of the larger site, the science behind each concept is explained using animations, an image gallery, video interviews, problems, biographies, and links. There are three sections, Classical Genetics, Molecules of Genetics and Organization of Genetic Material. Key features are the clear explanations of classical experiments and the excellent photographs of researchers and their labs.
