The subsequent breakdown of the nuclear envelope terminates prophase and ... traditional phases of mitosis (top) and our proposed transitions (bottom). Given that the early stages of chromosome ...

The two centriole pairs split at the onset of mitosis (M phase), in early prophase, thus forming two centrosomes; the two resulting microtubule asters then determine the bipolarity of the mitotic ...

Interphase The cell spends most of its life in this phase. The DNA in chromosomes copies itself ready for mitosis. Prophase The DNA in chromosomes and their copies condenses to become more visible.

Before each cell division, termed mitosis, the genetic information ... the team also succeeded in identifying which proteins in the early prophase are labeled with a phosphate group.
