MR. LIBASSI: Thank you. 
Francis Ruddle? 
DR. RUDDLE: My nane is Frank Ruddle. I speak 
4 for no organized group, but mainly for myself. I an 
5 a cell biologist and a geneticist, and I have been a 
6 faculty member in the Department of Biology at Yale 
7 University since 1961, in which I now serve as Chairman. 
8 At Yale I served previously as Chairman of 
9 the Biological Safety Advisory Committee, which regulates 
10 recombinant DNA research at our university. I an proud 
H of the fact that the City of New Haven is actively 
12 represented on that committee, and has been from the 
13 outset, and that all of our meetings have been, from 
14 the outset, advertised and open to the public.

1 7 the City of New Haven today to the implementation of 
18 the revised guidelines. I will come back to this point 
18 in a moment. 
2Q My professional interest is in somatic cell 
21 genetics. This discipline is concerned with an understanding 
22 of the genetic organization and function of mammalian 
23 chromosomes, especially those of man. An important 
24 technique in my study is cell hybridization, which 
25 permits one to literally fuse mouse and human cells to
