During very early prophase a big tip that the cell is no longer in interphase is that the nucleoli have disappeared and the nuclear material appears grainy.
During late prophase and begin to pull the chromosomes toward the equator of the cell.
Late prophase is sometimes given a special name Prometaphase because of the two distinct events that happen then, namely, the disintegration of the nuclear membrane and, the attachment of the chromosomes to the spindle.
