    Prophase is the first stage of mitosis in animal cells, ... Preprophase band is present along the cell wall from images 1–3, is fading in image 4, and disappears by ...

  3. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    Prophase is the first stage of division. The nuclear envelope begins to be broken down in this stage, long strands of chromatin condense to form shorter more visible strands called chromosomes, the nucleolus disappears, and the mitotic spindle begins to assemble from the two centrosomes.

    The leptotene stage, also known as leptonema, is the first of five substages of prophase I during meiosis, the specialized cell division that reduces the chromosome number by half to produce haploid gametes in sexually reproducing organisms.

    en.wikipedia.org/wiki/Zygotene

    Zygotene (from greek "paired threads" [1]) is the second stage of prophase I during meiosis, the specialized cell division that reduces the chromosome number by half to produce haploid gametes. It follows the Leptotene stage and is followed by Pachytene stage.

    Microtubule dynamics during preprophase and prophase in plant cell mitosis, modified from Donukshe et al. [1] The images follow a tobacco BY-2 cell through the first stages of mitosis (c. 12 minutes).

  9. Aster (cell biology) - Wikipedia

    en.wikipedia.org/wiki/Aster_(cell_biology)

    During mitosis, there are five stages of cell division: Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. During prophase, two aster-covered centrosomes migrate to opposite sides of the nucleus in preparation of mitotic spindle formation. During prometaphase there is fragmentation of the nuclear envelope and formation of the mitotic ...
