Solution:

Many species of bacteria may carry extrachromosomal genetic elements in the form of small circular and dosed DNA molecules called plasmids. One function of some of these plasmids is the production of antibiotically active proteins or colicins which inhibit the growth of other strains of baderia in their vicinity. Some plasmids may ad as sex or fertility fadors (F fador) which stimulate baderial conjugation.
