How can the Government insure the health and welfare of the 
public without intruding unnecessarily on the freedom of scien- 
tific inquiry? 
When is the commercial application of recombinant DNA tech- 
nology likely to begin? Do adequate Federal regulatory safe- 
guards exist to protect human beings and the environment from 
the potential hazards associated with large-scale use of this 
technology ? 
In addition to the testimony at the November hearings, the subcom- 
mittee received extensive supplementary material from witnesses and 
others. Federal agencies perceived to have any role in supporting or 
regulating recombinant DNA research or technology were asked 
whether existing statutes could provide an adequate basis for Federal 
controls. A list of those who submitted written statements and re- 
sponses to the subcommittees inquiries are found in the appendix.
