Which phase is not part of mitosis?

Explanation:
Recognizing what happens before, during, and after mitosis helps you see that interphase isn’t part of mitosis. Mitosis is the sequence of nuclear division stages where chromosomes condense, align, separate, and the nucleus reorganizes—typically listed as prophase, metaphase, anaphase, and telophase (often with cytokinesis following). Interphase is the period before these divisions, when the cell grows and carries out normal functions, and DNA is replicated during the S phase. The chromosomes are not condensed for segregation during interphase, and the nuclear envelope is intact for much of this phase. So, interphase is the time preparation happens, not a phase of mitosis itself.
