Mitotic prometaphase
WebIn prometaphase the nuclear envelope breaks down (in many but not all eukaryotes) and the chromosomes attach to the mitotic spindle. Both chromatids of each chromosome attach to the spindle at a specialized chromosomal region called the kinetochore. WebThe mitotic phase is the end of the cell cycle, concluding in cell division. During the mitotic phase, the DNA and cell structures that were duplicated in interphase, divide into two …

WebThe network of microtubules is the beginning of the mitotic spindle. It should be noted that some centrosomes contain a pair of centrioles that may help organize microtubule assembly. However, they are not essential to formation of the mitotic spindle, because plant cells that lack centrioles have no trouble undergoing mitosis. Prometaphase
