Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In what stage does the cytoplasm divide?
A
Interphase
B
Prophase
C
Metaphase
D
Cytokinesis
Explanation: 

Detailed explanation-1: -Cytokinesis starts during the nuclear division phase called anaphase and continues through telophase . A ring of protein filaments called the contractile ring forms around the equator of the cell just beneath the plasma membrane.

Detailed explanation-2: -M phase. During the mitotic (M) phase, the cell divides its copied DNA and cytoplasm to make two new cells. M phase involves two distinct division-related processes: mitosis and cytokinesis.

Detailed explanation-3: -The four stages of cytokinesis are initiation, contraction, membrane insertion and completion.

Detailed explanation-4: -Along with telophase, the cell undergoes a process called cytokinesis that divides the cytoplasm of the parental cell into two daughter cells.
