Interphase Metaphase Telophase O Prophase Anaphase QUESTION 28 Under the Microscope Identify which phase of mitosis you see in the image below. In telophase, the daughter chromosomes arrive at the spindle poles and are eventually redistributed into bulk chromatin. Individual chromosomes begin to decondense back into chromatin at this stage and start to become less clearly defined. After telophase is cytokinesis, which is not technically a phase because cytokinesis is the splitting of the cell, and mitosis refers to the division of the nucleus. Prophase Under a Microscope.
