Cytokinesis occurs during this stage of mitosis.
anaphase
500
This "packaging center" of the cell wraps proteins in their correct coating and ensures they make it to their proper destination.
What is the golgi body
500
"Sir Erwin's" discovery helped Watson and Crick figure out the base pairing in their DNA molecule.
