::Except that the growth pattern of the Cit+ cells in the third replay experiment demonstrated that there were no Cit+ cells in the cultures at the time of plating. Control plates with a mix of Cit- and Cit+ cells were done which showed rapid development of Cit+ colonies, whereas the experimental plates did not show any Cit+ colonies for at least 8 days and up to 28 days. If you believe that the plates became randomly contaminated during the course of the incubation, rather than at the initial plating, the post-plating contamination should have affected all generations equally, but it did not--[[User:Brossa|Brossa]] 12:46, 15 July 2008 (EDT)
