themselves, line up at the middle, then pull apart. Two identical
daughter cells come out the other end.
Notice: the chromosomes copy themselves before the cell divides — during
interphase, when you can't even see them. Then during anaphase they get pulled apart
to opposite ends. Each daughter cell ends up with the same number and type of
chromosomes as the parent. That's why mitosis produces identical clones — it's used
for growth and repair, not for making sex cells.
