LESSON 05 OF 16
Mitosis — Cell Division for Growth
Mitosis — PMAT
Mitosis produces 2 identical daughter cells. Used for growth, repair, asexual reproduction. Master the 4 phases.
PMAT
The Four Phases
P
Prophase
Chromatin condenses into visible chromosomes. Spindle fibres form from centrioles. Nucleolus disappears and the nuclear envelope breaks down.
M
Metaphase
Chromosomes align at the metaphase plate. Spindle fibres attach to centromeres.
A
Anaphase
Sister chromatids separate and are pulled to opposite poles. The cell elongates.
T
Telophase + Cytokinesis
Nuclear envelopes reform, chromosomes decondense, and the cell divides into 2 identical diploid cells.
2n→2n
Diploid to diploid
2
Genetically identical daughter cells
4
Phases: PMAT
3
Purposes: growth, repair, asexual reproduction

Exam tip
The phase where "sister chromatids separate" is always Anaphase — this exact wording is one of the most repeated MDCAT recall questions across past papers.
