Winding Your Way Through DNA

Excerpts from UCSF's 1992 symposium on biotechnology.

Three of the many topics presented at this important and informative symposium are available in About Biotech. The Bioethics section includes DNA on the Witness Stand, a discussion of DNA identification technologies. Biotech Applied (this page) links to Green Genes, a discussion of genetically modified food, and Biotech Chronicles includes From Corned Beef to Cloning, an account of the beginnings of recombinant DNA technology.
