Plasmids are possessed by eukaryotic cells
WebYet another difference between prokaryotes and eukaryotes is that prokaryotic cells often contain one or more plasmids (i.e., extrachromosomal DNA molecules that are either … WebPlasmids are small pieces of DNA which exist outside major chromosomes. Although virtually all plasmids are known from bacteria, some are known to exist in mitochondrial. A number of linear mitochondrial plasmids are known in fungi and higher plants, some of which require the presence of two plasmids in order to replicate (Chan, 1991).
