Detailed explanation-1: -Binary fission is different from mitosis because prokaryotic cells do not have a true nucleus like eukaryotes. Also, there is no mitotic spindle formation in the nucleus during binary fission.
Detailed explanation-2: -Binary fission occurs primarily in prokaryotes (bacteria), while mitosis only occurs in eukaryotes (e.g., plant and animal cells). Binary fission is a simpler and faster process than mitosis. The third main form of cell division is meiosis.
Detailed explanation-3: -Bacterial binary fission is similar in some ways to the mitosis that happens in humans and other eukaryotes. In both cases, chromosomes are copied and separated, and the cell divides its cytoplasm to form two new cells.
Detailed explanation-4: -In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA. Binary fission is the primary method of reproduction of prokaryotic organisms.
Detailed explanation-5: -The precise timing and formation of the mitotic spindle is critical to the success of eukaryotic cell division. Prokaryotic cells, on the other hand, do not undergo mitosis and therefore have no need for a mitotic spindle.
