Size of several pSU19-based plasmid constructs after growth under different Cm concentrations.

<p>An agarose gel is depicted. The arrow indicates the molecular size after IS10 insertion. T0, DNA used to transform cells at the beginning of the assay; T1, T2, T3, T4, and T6 refer to DNA obtained from cultures of different days. Cm concentration used is indicated in μg/ml, as Cm10 or Cm40.
