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 ...

Before each cell division, termed mitosis, the genetic information must first be duplicated ... the team also succeeded to identify which proteins in the early prophase are labeled with a phosphate ...
