CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the 3 main stages involves the cytoplasm dividing to form 2 daughter cells?
A
Interphase
B
Mitosis
C
Cytokinesis
D
None of the above
Explanation: 

Detailed explanation-1: -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-2: -Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. It occurs concurrently with two types of nuclear division called mitosis and meiosis, which occur in animal cells.

Detailed explanation-3: -Thus, cytokinesis can be considered to occur in four stages-initiation, contraction, membrane insertion, and completion.

Detailed explanation-4: -Cytokinesis begins in anaphase in animal cells and prophase in plant cells, and terminates in telophase in both, to form the two daughter cells produced by mitosis.

Detailed explanation-5: -The third stage of the cell cycle is called cytokinesis. During this stage, the cytoplasm of the cell divides to form two cells. These two cells are called daughter cells. The new daughter cells are exactly the same as each other.
