A particular Hfr strain normally transmits the pro+ marker as the last one during conjugation. In a cross of this strain with an F- strain, some pro+ recombinants are recovered early in the mating process. When these pro+ cells are mixed with F- cells, the majority of the latter are converted to pro+ cells that also carry the F factor. This job furthger explains these results.© BrainMass Inc. brainmass.com April 3, 2020, 1:35 pm ad1c9bdddf
Recombination in bacteria is featured. The mating processes and pro+ markers are examined.
