Telophase - Definition and Stages in Mitosis and Meiosis Biology ...

WebTelophase: The spindle apparatus breaks down, and the chromosomes begin to unwind back into chromatin. The nuclear envelope reforms around each set of chromosomes, creating two new nuclei. Finally, the cell undergoes cytokinesis, where the cytoplasm divides, forming two identical daughter cells, each with 2n=2 chromosomes. WebSpindle microtubules that do not engage the chromosomes are called polar microtubules. These microtubules overlap each other midway between the two poles and contribute to cell elongation. Astral microtubules are located near the poles, aid in spindle orientation, and are required for the regulation of mitosis.
