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… WebHaploid cells contain one set of chromosomes. Cells containing two sets of chromosomes are called diploid. The number of sets of chromosomes in a cell is called its ploidy level. ... Thus, meiosis I is the first round of meiotic …

"WebFeb 4, 2024 · Prometaphase is often referred to as “late prophase.” (Though it’s also sometimes called “early metaphase” or referred to as a distinct phase entirely!) Regardless, some really important things occur during prometaphase that propel cell division along and that help explain what happens in metaphase. " - In a prometaphase cell
