Interphase

What occurs before mitosis begins?

Chromosomes are copied and double in number.

What is the first step in mitosis?

Prophase, where the nuclear membrane breaks down and spindle fibers form.

What happens during Prophase?

Chromosomes appear as chromatids, and centrioles begin to move toward opposite ends of the cell.

What is the second step in mitosis?

Metaphase, where chromatids line up along the equator of the cell and attach to spindle fibers.

What occurs during Anaphase?

Chromatids separate and move to opposite ends of the cell.

What is the third step in mitosis?

Anaphase, where chromatids are separated.

What is the fourth step in mitosis?

Telophase, where two new nuclei form and chromosomes return to chromatin.

What happens during Cytokinesis?

The cell membrane moves inward to create two daughter cells, each with an identical nucleus.

What follows mitosis?

Cytokinesis occurs after mitosis, finalizing the cell division process.

What is the role of spindle fibers?

Spindle fibers attach to the chromatids and help separate them during mitosis.
