11 Although scientists have been aided by the 
12 powerful new tool of recombinant DNA technology for only 
13 a few years, dramatic advances in the understanding of 
14 genetics, the structure and organization of chromosomes, 
15 and the detailed regulatory processes controlling repl i- 
16 cation and metabolism have already been published. This 
17 new knowledge has provided a more sound basis for modern 
18 concepts of many processes jf metabolism in normal and 
19 diseased organisms. Practical applications for health 
20 care, agriculture, and environmental protection have 
21 appeared more slowly, yet significant progress has been 
22 reported in producing materials of potential value to 
23 society. 
24 The proposed Revised Guidelines for Recombin- 
25 ant DNA Research are reasonable, cautious, and careful
