Detailed explanation-1: -Anaphase is the fourth step in mitosis. In anaphase, cohesin proteins binding the sister chromatids together break down. sister chromatids (now called chromosomes) are pulled toward opposite poles.

Detailed explanation-2: -Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).

Detailed explanation-3: -Mitosis takes place in four stages: prophase (sometimes divided into early prophase and prometaphase), metaphase, anaphase, and telophase.

Detailed explanation-4: -Anaphase in Mitosis Anaphase of cell mitosis is the third phase of the active cell division process. It happens after the prophase and metaphase stages. Sister chromatids are joined at the centromeres; they need to be separated next.
