Dear Dr. Fredrickson: 
The purpose of this letter is to express my support on revised 
guidelines for recombinant DNA research as published in the Federal 
Register, November, 1979. Of particular importance is the need not 
to impede the conduct of experiments using £. col i K- 12 host vector 
systems. 
In my judgment, the NIH Recombinant DNA Advisory Committee is 
to be commended for their outstanding task regarding DNA research.
