Mitosis — Cell Division

Stage 1 / 6 — Interphase
MOTHER CELL — 2 chromosomes Interphase — chromosomes exist as thin, uncoiled chromatin threads
MOTHER CELL — 2 chromosomes Prophase — chromatin coils tightly into cross-shaped chromosomes
MOTHER CELL — 2 chromosomes Metaphase — spindle fibers line chromosomes up at the cell's centre
MOTHER CELL — 2 + 2 chromosomes separating Anaphase — spindle fibers shorten, pulling one full copy to each pole
DAUGHTER CELL A — 2 DAUGHTER CELL B — 2 Telophase — two new nuclear envelopes re-form as the cell pinches inward
DAUGHTER CELL A — 2 DAUGHTER CELL B — 2 Cytokinesis — nuclear envelopes complete; each daughter matches the mother cell

Interphase: the cell grows and its DNA replicates while chromatin remains loosely coiled inside an intact nucleus.
