Multiple Choice
Which phase of mitosis is shown in the diagram, where sister chromatids have separated and are moving toward opposite poles of the cell?
A
Metaphase
B
Telophase
C
Prophase
D
Anaphase
Verified step by step guidance1
Recall the key events that characterize each phase of mitosis: Prophase involves chromosome condensation and spindle formation; Metaphase is when chromosomes align at the metaphase plate; Anaphase is when sister chromatids separate and move toward opposite poles; Telophase involves the reformation of the nuclear envelope and chromosome decondensation.
Identify the specific event described: sister chromatids have separated and are moving toward opposite poles. This is a critical clue because it indicates the chromatids are no longer paired.
Match this event to the corresponding mitotic phase. Since sister chromatids separate and migrate during Anaphase, this phase fits the description perfectly.
Confirm that the other options do not fit: Metaphase shows chromosomes aligned but not separated; Prophase involves chromosome condensation but no separation; Telophase occurs after chromatids have reached poles and involves nuclear reformation.
Conclude that the phase shown in the diagram, where sister chromatids have separated and are moving toward opposite poles, is Anaphase.
