In February 1975, leading biology researchers and lawyers participated in what became known as the Asilomar Conference, a meeting to discuss and recommend policy regarding novel recombinant DNA, or rDNA, technology. rDNA is DNA that scientists create in a lab by combining genetic material from two distinct sources. A group of researchers, including Paul Berg, Maxine F. Singer, and David Baltimore, organized the Asilomar Conference, which was held at the Asilomar Conference Grounds in Pacific Grove, California. The purpose was to discuss how to manage the risk of researchers unintentionally creating harmful or deadly pathogens through rDNA research. The conference resulted in the creation of the NIH Guidelines for Research Involving Recombinant DNA Molecules in 1976, which outlines biosafety guidelines for researchers working with rDNA. The Asilomar Conference was one of the first instances when scientists gathered independently to discuss and establish precautionary guidelines for research using rDNA, a technology with the potential for wide-reaching applications for medicine, biology, and reproduction.
