Final answer:
Prokaryotic cells are cells without a nucleus. They contain DNA in the cytoplasm and have a central region called the nucleoid. Some prokaryotes have plasmids outside the nucleoid, which transfer genes between cells. Prokaryotic cells divide by binary fission and do not have membrane-enclosed organelles.
Step-by-step explanation:
Prokaryotic cells are cells without a nucleus. The DNA in prokaryotic cells is in the cytoplasm rather than enclosed within a nuclear membrane. Prokaryotic cells are found in single-celled organisms, such as bacteria. The central region in prokaryotic cells where the DNA resides is called the nucleoid region. Some prokaryotic cells also have smaller DNA structures outside the nucleoid region called plasmids, which can transfer genes between cells and carry certain traits. Prokaryotic cells divide by binary fission, do not have membrane-enclosed organelles, and do not sexually reproduce. Instead, the transfer of DNA in prokaryotes happens through a process called conjugation, where only DNA fragments are transferred.
