WebNov 30, 2015 · The very early decrease in band numbers in early prophase (see Fig 3) indicates a coalescence of the 30-nm fiber loops (a conventional definition because of a current debate) that form the bands. Obviously, the transition from the loops of interphase chromatin to the 30-nm fiber loops of early prophase needs a transient intermediary step. WebApr 29, 2024 · The cell cycle contains two distinct phases: interphase (also called I phase) and mitosis (also called M phase). During interphase, the cell prepares to divide by undergoing three subphases known as G 1 phase, S phase and G 2 phase. Some cells remain in interphase for days or even years; some cells never leave interphase.
