Verified step by step guidance1
Understand the process of mitosis: Mitosis is divided into several stages—prophase, metaphase, anaphase, and telophase—each with specific cellular events.
Recall the definition of cytokinesis: Cytokinesis is the process where the cytoplasm of a parent cell is divided into two daughter cells, completing cell division.
Identify the stage of mitosis where cytokinesis begins: Cytokinesis typically starts during the later stages of mitosis, as the cell prepares to fully divide.
Analyze the events of telophase: During telophase, the nuclear envelope re-forms around the separated chromosomes, and the cell begins to physically divide, marking the onset of cytokinesis.
Conclude that cytokinesis typically begins during telophase, as this is when the cell starts to split into two distinct daughter cells.
