A critical tool in genetic engineering, For ten points, name for these circular DNA rings found in bacteria which are separate from the main chromosome of the host.
They can be removed with intercalating dyes or incubation at elevated temperatures, a process called curing, and they can be inserted with a combination of calcium chloride and heat, a process called tranformation. Conjugative ones include tra-genes, and cells containing them are denoted F-positive. Episomes are ones that can reversibly integrate into the host chromosome. Col factors have genes coding for colicines, which have antibacterial action, and R factors confer resistance.
