The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid. This sits in the cytoplasm of the bacterial cell.
The three ways in which genetic recombination occur in bacteria are: 1  Tranformation-bacteria are able to take up foreign DNA through their cell membranes. 2  This foreign DNA most often remains as an extrachromosomal structure called the plasmid.
