WebWhen copies of the plasmid are mixed with E. coli cells and the cells are heat-shocked (exposed briefly to high temperature), a small fraction of them will take up the plasmid. All of the E. coli are then spread on a nutrient plate containing the antibiotic. The purpose of the antibiotic is to only let bacteria with the plasmid survive and grow. WebPlasmids contain just a few genes, but they make a big difference to their host bacterium. The genes are usually not essential for the bacteriums day-to-day survival – instead, they help the bacterium to overcome occasional stressful situations.Bacterial plasmids may encode genes for traits that are sometimes beneficial to their hosts, such as antimicrobial …
