Prokaryotic cells — like bacteria — do not have a nucleus. Unlike human cells, which store DNA inside a membrane-bound nucleus, prokaryotes keep their genetic material loose in the cell. This is the single biggest difference between the two major cell types on Earth. Red blood cells in humans also lose their nucleus as they … Read more
