Which process do most prokaryotic cells use to divide?

• A. Meiosis
• B. Mitosis
• C. Binary fission
• D. Budding

Answer: (C)

Binary fission is the typical way most prokaryotes divide. These cells lack a nucleus, so they don’t use the mitotic machinery that eukaryotes rely on. The process starts with copying the circular chromosome, then the cell grows and a septum forms to pinch the cell membrane and wall inward, splitting the cell into two new, usually identical, daughter cells. This simple, rapid method suits the streamlined structure of prokaryotic cells. Meiosis and mitosis require a nucleus and spindle apparatus, which prokaryotes don’t have, so they aren’t used by these organisms. Budding can occur in some organisms but is not the standard division method for the majority of prokaryotes.
