Two structural types of bacterial linear DNA have been characterized. … Linear genomic structures are probably more common in bacteria than previously recognized, however, and some replicons may interconvert between circular and linear isomers.

Do prokaryotes have linear chromosomes?

In most eukaryotic cells, DNA is arranged in multiple linear chromosomes. In contrast, most prokaryotic cells generally contain a singular circular chromosome. However, linear chromosomes are not limited to eukaryotic organisms; some prokaryotic organisms have linear chromosomes as well, such as Borrelia burgdorferi.

Does bacteria have linear or circular DNA?

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.
