  • Conjugation and Transposition in Escherichia Coli
    Abstract The purpose of this experiment was to study the transfer of genetic information on plasmid F’lac by using Escherichia coli. Plasmid transfer was measured by using two different methods. The first one was by using selection and contraselection with three antibiotics: streptomycin(which was replaced by naladixic acid for the second part of the experiment),ampicillin and kanamycin and the second one by using a colour indicator ( X-gal). As significant results, the percentage of transfer...
