Detailed explanation-1: -Mitosis without cytokinesis results in a cell with more than one nucleus but a connected cytoplasm (syncytium). A multinucleated cell is one with several nuclei. This might be a normal occurrence. Humans, for example, have multinucleated bone cells (osteoclasts) that originate in this manner.
Detailed explanation-2: -Cytokinesis usually, but not always, follows mitosis. If a cell undergoes mitosis and not cytokinesis, this would result in 2 cells without nuclei O a cell with two or more nuclei. cells with abnormally small nuclei. a cell with a single large nucleus.
Detailed explanation-3: -A mitotic cell cycle in which mitosis is completed but cytokinesis does not occur, resulting in a cell containing multiple nuclei each with a chromosomal complement of the original ploidy (usually 2N).
Detailed explanation-4: -Cytokinesis usually follows mitosis.
Detailed explanation-5: -In a typical cell, cytokinesis accompanies every mitosis, although some cells, such as Drosophila embryos (discussed later) and vertebrate osteoclasts (discussed in Chapter 22), undergo mitosis without cytokinesis and become multinucleate.
