Answer:
The second and last phase which is cytokinesis is missing in the cell cycle.
Explanation:
A cell division into two daughter cell involves two phases:
Karyokinesis: The division of the cell nucleus. It further involves many steps like prophase interphase metaphase etc. After this phase cell contains two daughter nuclei.
Cytokinesis: This the division of the cytoplasm of the cell and having the formation of a cell membrane in the middle of the cell separating two daughter nuclei into two distinct cells.
If karyokinesis proceeds but cytokinesis does not proceed. It leads to the multinucleated cell.
