During mitosis, after the chromosomes have lined up in the middle of the cell, what occurs in the next phase?
A
The sister chromatids are pulled apart to opposite poles of the cell.

Verified step by step guidance
1
Understand that mitosis is a process of cell division that results in two genetically identical daughter cells.
Recognize that the phase where chromosomes line up in the middle of the cell is called metaphase.
After metaphase, the next phase is anaphase, where the sister chromatids are pulled apart to opposite poles of the cell.
During anaphase, the spindle fibers shorten, pulling the chromatids toward the poles, ensuring each new cell will receive an identical set of chromosomes.
Following anaphase, the cell will proceed to telophase, where the nuclear envelope re-forms around the separated chromosomes, and cytokinesis will occur, splitting the cell into two daughter cells.
