M Phase: What Happens in this Phase of the Cell Cycle?

Prometaphase is the phase of mitosis following prophase and preceding metaphase in eukaryotic somatic cells. In prometaphase, the nuclear membrane breaks apart into numerous "membrane vesicles," and the chromosomes inside form protein structures called kinetochores. Kinetochore microtubules emerging from the centrosomes at the poles (ends) of the spindle reach the chromosom… WebMeiosis II, in which the second round of meiotic division takes place, includes prophase II, prometaphase II, and so on. Meiosis I Meiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. drake bird image https://stampbythelightofthemoon.com
