Solution
Each chromosome separates into two daughter chromosomes by binary fission.
Explanation:
Binary fission is a simple type of cell division used by bacteria (prokaryotes), not by the complex cells of multicellular organisms. In multicellular organisms, chromosomes are separated through mitosis or meiosis, which involve a complex spindle system to pull them apart. The other statements are true: chromosomes are made of DNA and protein, they double into two chromatids during the S-phase, and every cell in your body generally carries the same genetic blueprint.
