Revised guidelines covering the conduct of recombinant DNA 
research were announced by the Secretary December 17. The new 
guidelines increase public participation significantly at both 
the local and national level in the advisory and biosafety 
committees the program requires. 
Recombinant DNA molecules contain segments of DNA which have 
been combined in the test tube. The research techniques used to 
produce recombined molecules of deoxyribonucleic acid (DNA) , the 
complex chemical that codes genetic information for all living 
cells, hold promise for advancing the understanding cf fundamental 
biological processes. Moreover, this research may also have 
potential for the commercial production of needed biological 
materials and agricultural products. 
A complete list of members of the Recombinant DNA Advisory 
Committee is attached.
