Which step of mitosis involes chromosomes lining up in the center of the cell? •metaphase
•prophase
•anaphase
•telophase

Metaphase is the step in mitosis that involves the chromosomes to line up in the middle. Another way you can remember it is that Metaphase starts with the same letter as Middle.
Hope it helps!

During metaphase, the chromosomes align at the center of the cell. During anaphase, the sister chromatids are separated and pulled to opposite ends of the cell. During telophase, the nuclear envelope begins to re-form around the divided chromatids.
