Phases of the Cell Cycle
Phase Stage Description
Interphase
(longest phase)
G1 growth, organelle replication and the cell functions (longest stage)
S (synthesis) DNA (chromosomes) replicated and the cell functions
G2 growth, organelle replication and cell functions -prep for division
Mitotic (M) Phase
Mitosis nuclear division (PMAT) → 2 nuclei
M cell division → 2 identical daughter cells
Phases of Mitosis
Prophase Chromosomes condense, nuclear membrane breaks down, mitotic spindle forms
Metaphase Chromosomes align at the center of the cell
Anaphase Sister chromatids separate and move towards opposite poles of the cell
Telophase Chromosomes decondense, nuclear membrane reforms, cell begins to divide
Cytokinesis Division of the cytoplasm to form two separate daughter cells
