Question

Which phase of mitosis involves the separation of sister chromatids?

Tap to reveal answer

Answer

Mitosis is composed of four primary phases: prophase, metaphase, anaphase, and telophase.

During prophase the chromosomes condense, the nuclear membrane dissolves, and spindle fibers begin to form. Metaphase marks the time when the chromosomes align at the center of the cell and the spindle fibers attach to the centers of the chromosomes. During anaphase, the spindle fibers contract, separating the sister chromatids and pulling them toward opposite poles of the cell. Telophase marks the beginning of cytokinesis, when the cell fully divides, and the nuclear membrane reappears.

The correct answer is anaphase.
