At what phase of mitosis do chromosomes arrive at opposite poles of the cell?

During telophase, chromosomes have reached opposite poles of the cell and begin to decondense back into chromatin, signaling the end of mitosis. This phase is crucial because it involves the reformation of the nuclear envelope around the separated sets of chromosomes, ensuring that each new daughter cell will have a complete set of genetic material. Telophase is the stage where the physical separation of the genetic material is finalized, making it an integral part of the cell division process.

The other phases involve different activities: Prophase is characterized by the condensation of chromatin into distinct chromosomes, Metaphase is when chromosomes align at the cell's equatorial plane, and Anaphase involves the actual separation of chromatids and their movement toward opposite poles. Understanding these stages is vital for grasping how cell division is organized and regulated.
