A kinetic analysis of cell division, and induction and stability of recA protein in U.V. Irradiated ion+ and ion-strains of Escherichia coli K12.

Kinetic analysis of induction of recA protein synthesis after U.V. irradiation does not show correspondence with the kinetics of division inhibition in ion+ and ion- strains. When the induction of recA protein after U.V. is drastically reduced by rifampicin treatment, no effect on the kinetics of division inhibition is observed.
