The "pre" version of this occurs only in plants and forms a namesake microtubule band underneath the cell membrane. Before this stage can begin in some plant cells, a phragosome must be formed to bisect large vacuoles. Molecular motors drive the centrosomes apart during it, and microtubules connected to the centrosomes form the spindle apparatus. During it, the nucleolus disappears and, at its end
The "pre" version of this occurs only in plants and forms a namesake microtubule band underneath the cell membrane. Before this stage can begin in some plant cells, a phragosome must be formed to bisect large vacuoles. Molecular motors drive the centrosomes apart during it, and microtubules connected to the centrosomes form the spindle apparatus. During it, the nucleolus disappears and, at its end, the nuclear membrane dissolves. Condensin facilitates the chromatin condensation of this phase and each chromosome that forms during it contains two chromatids connected by a centromere. FTP, name this first stage of mitosis.
