Prophase
Prophase is a stage of mitosis .In
prophase the genetic material ( DNA ), which normally exists in the form of chromatin , condenses into a highly ordered structure called a chromosome . Since the genetic material has been duplicated, there are two identical copies of each chromosome in the...

prophase and followed by anaphase. See also cytokinesis prometaphase telophase anaphase...
