Master Telophase with Picmonic for Pre-Health

Telophase is the fourth phase of cell division and is characterized by the physical splitting of the original cell into two daughter cells. Cytokinesis occurs during telophase and is the process of separating the plasma and organelles between each daughter cell. In meiosis I telophase, the cell has now become haploid because each daughter cell only has one parent’s genetic information for each chromosome (1-23). The other parent’s chromosomes are in the other daughter cell. This is known as reductional division. In meiosis II telophase, the new daughter cells are haploid and the original cell was also haploid. This is because meiosis II picks up where meiosis I leaves off, and meiosis I left off with two haploid cells. Those haploid cells have an extra copy of a chromatid from each parent and split the two sister chromatids into individual daughter cells. In mitosis telophase, the new daughter cells are diploid and the original cell was also diploid. This is because in prophase, homologous chromosomes DO NOT pair and instead line up independently on the metaphase plate. Thus, each cell gets one chromatid from each parent for each of the 23 chromosomes, resulting in diploid daughter cells. Finally, the chromosomes decondense from chromatids to chromatin allowing the genetic information to be read by polymerase again. The nuclear membrane reforms and the nucleoli re-appear, finalizing the creation of two complete daughter cells.
