Copying DNA
(Interphase)

Before mitosis begins,
chromosomes are
copied. Each
chromosome is then
two chromatids.

Phase 1
(Prophase)
Click to listen
When mitosis begins,
the nuclear membrane
dissolves.
Chromosomes condense
into rodlike structures.

Phase 2
(Metaphase)

Then the chromosomes
line up along the middle
part of the cell.
Corresponding
chromosomes pair up.

Phase 3
(Anaphase)

The chromatids
separate and move to
opposite sides of the
cell.

Phase 4
(Telophase)
Click to listen
A nuclear membrane
forms around each set
of chromosomes, and
the chromosomes
unwind. Mitosis is
complete.

In cells that lack a cell
wall, the cell pinches in
two.
