There are two major processes that occur during cell division, often in an overlapping manner
as a cell divides into two new daughter cells. There are cytoplasmic division or ______________
and nuclear division or ____________. - ANS cytokinesis ; mitosis
Events that occur during different phases of the cell cycle are listed below. Match these phase
events to the phase that they occur in by drawing a line between them below.
