Explanation:
Detailed explanation-1: -All eukaryotic cells prepare for cell division by forming a “mitotic spindle ‘’-a bipolar machine made from microtubules (MTs) and many associated proteins. This device organizes the already duplicated DNA so one copy of each chromosome attaches to each end of the spindle.
Detailed explanation-2: -Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing.
