Baltimore also helped Paul Berg and Maxine Singer to organize the Asilomar Conference on Recombinant DNA, held in February 1975. The conference discussed possible dangers of new biotechnology, drew up voluntary safety guidelines, and issued a call for an ongoing moratorium on certain types of experiments and review of possible experiments, which has been institutionalized by recombinant DNA advisory committees established at essentially all US academic institutions conducting molecular biology research. Baltimore was well aware of the importance of the changes occurring in the laboratory: "The whole Asilomar process opened up to the world that modern biology had new powers that you had never conceived of before."
