What is the phase in which karyokinesis occurs during cell division?

Karyokinesis, the division of the cell nucleus, occurs during the M phase of the cell cycle. The M phase is the shortest phase of the cell cycle and consists of four stages: prophase, metaphase, anaphase, and telophase, followed by cytokinesis, which completes the process of cell division. The M phase is also known as the mitotic phase, and it is responsible for the formation of two genetically identical daughter cells.
