The mitotic spindle continues to form by microtubules that stretch to unify both ends of the spindle. The kinetochore attaches sister chromatids to the microtubules at the centromere (Fowler et al., 2021).]]> 2022-02-04 15:47:18 UTC https://padlet.com/marfrapep/Mitosis_and_Meiosis/wish/2029664259 marfrapep https://padlet.com/marfrapep/Mitosis_and_Meiosis/wish/2029690943 Chromosomes are aligned at the metaphase plate while each is attached to a kinetochore microtubule. The metaphase plate (location) is in the middle between the asters (Phases, n.d). Chromosomes are still very condensed, and the sister chromatids are attached (Fowler et al., 2021).]]> 2022-02-04 16:02:51 UTC https://padlet.com/marfrapep/Mitosis_and_Meiosis/wish/2029690943 marfrapep https://padlet.com/marfrapep/Mitosis_and_Meiosis/wish/2029707608 The sister chromatids are pulled apart towards the cell's pole by the microtubules as the cell stretches.

The chromosomes move toward each pole and are not tightly condensed anymore.

During anaphase in animal cells, this process happens by forming a cleavage that helps complete the division. Conversely, cytokinesis happens on telophase in plant cells. It creates a cell plate that eventually becomes the cell wall for each new cell.

In turn, a total of four cells are formed during meiosis. The independent assortment of the paired chromosomes (which exchanged part of their DNA through crossover) in metaphase I contribute to creating four genetically unique cells after meiosis II.]]> 2022-02-04 16:56:00 UTC https://padlet.com/marfrapep/Mitosis_and_Meiosis/wish/2029785192 marfrapep https://padlet.com/marfrapep/Mitosis_and_Meiosis/wish/2029807891 The number of chromosomes set is reduced in half, from two to one (Fowler et al., 2021).
Prophase I: Chromosomes pair with an equivalent one to exchange a portion of their DNA (Phases, n.d.).
Metaphase I: The pairs align randomly at the metaphase plate in the middle of the mitotic spindle.
Anaphase I: The matching pairs separate and move towards each end of the cell. The sister chromatoids remain attached.
Telophase I: The chromosomes reach the opposite poles of the cell, eliciting the creation of the nuclear membrane.]]> 2022-02-04 17:02:14 UTC https://padlet.com/marfrapep/Mitosis_and_Meiosis/wish/2029807891 marfrapep https://padlet.com/marfrapep/Mitosis_and_Meiosis/wish/2029827699 The process is less complex than Meiosis I, and it is a lot more similar to mitosis:
Prophase II: Chromosomes condense, the nuclear membrane breaks, and the nucleus disappears. (Phases, n.d.). Microtubules stretch and attach to each end of the spindle.
Metaphase II: Chromosomes align on the metaphase plate in the middle of the spindle.
Anaphase II: The microtubules separate the sister chromatids and pull them towards each cell pole.
Telophase II: A nuclear membrane forms around each group of decompressed chromosomes.
