WebIn meiosis I the sister chromatids stay together. This is different to what happens in mitosis and meiosis II. 5. Telophase I and cytokinesis: The chromosomes complete their move to the opposite poles of the cell. At each pole of the cell a full set of chromosomes gather together. A membrane forms around each set of chromosomes to create two ... WebOct 4, 2024 · The alignment of the chromosomes, with sister chromatids on each side of the metaphase plate ensures the two new cells will be identical. The sister chromatids represent the two new strands of DNA created from one chromosome during the synthesis stage of interphase. By separating all of these copies into new cells, the two new cells … WebThe chromatids are now called sister chromosomes as they are at the equator of the cell. Telophase 2: This stage is similar to the telophase 1 stage in Meiosis 1. Here, the chromosomes decondense, the nuclear membrane reforms and cell plate formation creates four haploid daughter cells.
