What happens to the chromosomes during mitosis?
To put it simply, during Mitosis the chromosomes are first replicated (copied) and then distributed into 2 new “daughter” cells. They are replicated during the S phase of interphase, and in the following phases (prophase, metaphase, anaphase, telophase) are organized, separated, and repackaged at opposite ends of the cell, at which point the cell divides.
