Scientists confronted with local controversy over recombinant DNA research, also referred to as gene cloning, often turned
to Singer for advice and information on how to counter the arguments of opponents and defend the safety of this research.

Letter from Maxine Singer to Milton P. Gordon (March 22, 1977)
I have enjoyed reading your recent comments about the question of cloning of DNA. Enclosed you will find a preprint that I
thought would be of interest to you. Essentially what our group here in Seattle has found is that the prokaryotic/eukaryotic
barrier as postulated by Sinsheimer does not occur in nature. We have found that a small portion of a plasmid present in Agrobacterium
tumefaciens is transferred to plant tissue in the course of producing tumors in the
I probably will be interviewed over a local radio station in the next couple of weeks. I would be very grateful if you could
send me any sort of general literature that you may have. Stanley Cohen's recent article in Science, I thought, was very
well taken; although some of the people at the University of Washington who have opposed DNA cloning experiments have pointed
out a couple of weak points in his arguments. Anything you have along these lines would be very helpful, as I feel I might
be in for a hard time during the course of the program.
