Web9 jan. 2024 · Genetic information in prokaryotic cells is carried on a single circular piece of DNA which is attached to the cell membrane and in direct contact with the cytoplasm. There is no enclosing membrane, so there is no true nucleus, but simply a concentration of DNA known as a nucleoid. How is DNA arranged and packaged in prokaryotic cells? WebFlagella (singular = flagellum) are long, hair-like structures that extend from the plasma membrane and are used to move an entire cell, (for example, sperm, Euglena ). When present, the cell has just one flagellum or a few flagella. Prokaryotes sometimes have flagella, but they are structurally very different from eukaryotic flagella.
