Not all cells have a nucleus. Biology breaks cell types into eukaryotic (those with a defined nucleus) and prokaryotic (those with no defined nucleus). ... You don't need a nucleus to have DNA. If you don't have a defined nucleus, your DNA is probably floating around the cell in a ...
(CO) show that the cell clusters have more of the enzyme and, presumably, higher metabolic activity than the surrounding fiber regions. The details of the parcellation pattern of this nucleus in humans and monkeys are quite comparable (Florenceet al.,1989), suggesting the significance of the ...
