August 8, 1977 The Honorable Paul N. McCloskey 305 Grant Avenue Palo Alto, California 94306 Dear Pete: I am grateful for what I take to be your interest in putting a brake on recombinant DNA legistation. Already, the misguided features of the Kennedy bill in the Senate are widely appreciated. Senator Gay- lord Nelson has made it very clear that the need to regulate indurtrial activity is already met by available Federal statutes and that repres- sive state and local statutes can be preempted without imposing equally foolirsh Federal laws. You sent me the l'Backgrounder on Recombinant DNA Reoearch" I cannot answer it point I find the whole tone and subrtance of this (prepared by John Bartenstein, July 20, 1977). by point as you aaked me to. eaeay to be so grossly inept that analysis of its detail8 aeems futile. To begin with the very first sentence: There wals no major breakthrough at Stanford in 1973! What Stanley Cohon achieved was a significant step in an orderly train of releearch that can be traced accurately for at leart the past 25 to 50 years. The enzymes baric to recombinant DNA research had been known for many years and their application to joining chromoromal fragments wae an inevitable link in our attempt to understand the heredi- tary and metabolic machinery of the cell. Congress could retard this march of science in the U. S., aa Lysenko did in genetics in the Soviet Union for a whole generation, but romewhere in the world it will pro- ceed. Recombinant DNA research ir not a Pandora's box. There is no single instance or example to suggest that this research has a potential for harm any more than any other avenue of rerrearch in medical science today. Pete, I invite you to have lunch with me and some of my colleagues the next time you are in the Dietrict to give us a chance to give you a more substantial background on this whole issue. With warm regards, Sinc erely, Arthur Ko rnbe r g AK/i
