In this study … WebIn prokaryotes (bacteria), the genome is composed of a single, double-stranded DNA molecule in the form of a loop or circle. The region in the cell containing this genetic material is called a nucleoid. Some prokaryotes also have smaller loops of DNA called plasmids that are not essential for normal growth. Figure 1 An average prokaryotic cell.

WebBacterial and archaeal DNA is organized differently from eukaryotic DNA. While eukaryotic DNA is contained in a nucleus, bacterial and archaeal DNA is contained in the cytoplasm, where it is organized into a single, circular chromosome. This chromosome is not associated with histone proteins, as in eukaryotes, and does not have introns or exons.
