Is cytokinesis a phase in mitosis?

No, cytokinesis is separate from mitosis. It is the splitting of the cytoplasm, which occurs after mitosis. Mitosis can occur without cytokinesis, resulting into two nuclei in one cell. read more

Cytokinesis (/ ˌ s aɪ t oʊ k ɪ ˈ n iː s ɪ s /) is the part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells. Cytoplasmic division begins during or after the late stages of nuclear division in mitosis and meiosis. read more

Telophase and Cytokinesis   The final two events of M phase are the re-forming of the nuclear envelope around the separated sister chromatids and the cleavage of the cell. read more

Cytokinesis is the final phase of cell division during meiosis, just as it is with mitosis, where the cytoplasm of two daughter cells is separated by a cell membrane or cell wall. In animal cells, this is accomplished by pinching the cell membrane closed with a ring of actin and myosin proteins, the same proteins that are used in muscle contraction. read more
