    • Chromosomal DNA
      Single, large loop of circular DNA, contains most of the cell's genetic information
    • Plasmid DNA
      Small, self-replicating circles of DNA, found freely in cytoplasm, carry specific genes or functions
    • Natural Habitat of Genetic Material in Prokaryotic Cells

      Cytoplasm, not within a nucleus
    • Prokaryotes do not have membrane-bound nuclei; their genetic material is contained in a single, circular molecule of double-stranded DNA.
    • Eukaryotes have linear chromosomes that are tightly coiled around proteins called histones.
    • Apart from chromosomal DNA, prokaryotic cells may also contain plasmid DNA, which are small, self-replicating circles of DNA found freely in the cytoplasm and carrying specific genes or functions.
    • In prokaryotic cells, chromosomal DNA is typically organized as a single, large loop of circular DNA containing most of the cell's genetic information.
    • Prokaryotic cells lack a membrane-bound nucleus to house their genetic material, which is found in the cytoplasm.
    • The number of chromosomes varies between species but is constant for an individual organism.
