Understand that 'PMAT' is an acronym used to describe the four main stages of mitosis, which is the process of nuclear division in eukaryotic cells.
Identify each letter in 'PMAT' as representing a specific phase: P for Prophase, M for Metaphase, A for Anaphase, and T for Telophase.
Recall the key events in each phase: Prophase involves chromosome condensation and spindle formation; Metaphase aligns chromosomes at the cell equator; Anaphase separates sister chromatids to opposite poles; Telophase re-establishes the nuclear envelope around the separated chromatids.
Differentiate these mitotic phases from the broader cell cycle phases, which include G1, S, G2, and M phases, where 'M' encompasses mitosis and cytokinesis.
Recognize that 'PMAT' specifically refers to the sequence of stages within mitosis, not to DNA replication during S phase or cytokinesis.
