At a point in the cell cycle, chromosomes have aligned near the middle of a cell. Which sequence of events will the cell need to complete to produce two identical daughter cells?

• anaphase → telophase → cytokinesis

• anaphase II → telophase II → cytokinesis II

• prophase → metaphase → anaphase

• metaphase II → anaphase II → telophase II
