Dna is stored linearly in a nucleus within
WebIn prokaryotic cells, the DNA is mostly located in a central part of the cell called the nucleoid, which is not enclosed in a nuclear membrane. Most of the genetic material in most prokaryotes takes the form of a single circular DNA molecule, or chromosome. In addition, many prokaryotes also contain small circular DNA molecules called plasmids. WebDNA is normally found as a loosely contained structure called chromatin within the nucleus, where it is wound up and associated with a variety of histone proteins. When a cell is about to divide, the chromatin coils tightly and condenses to form chromosomes. There is a pool of cells constantly dividing within your body.

WebKey points: Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide. WebA nucleus is a membrane-bound organelle that houses the genetic material of eukaryotes in DNA. The nucleus consists of protein fibres or the DNA inside chromatin fibres. Nucleoids contain the genetic material of prokaryotes in the cytoplasm. ... Nucleoid Meaning By definition, a nucleoid is a region within a prokaryotic cell that contains most ...
