CELL DIVISION

THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The nucleus divides into 2 nuclei during ____
A
Mitosis
B
Replication
C
Cytokinesis
Explanation: 

Detailed explanation-1: -Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word “mitosis” means “threads, ” and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.

Detailed explanation-2: -In telophase, the cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place. The mitotic spindle is broken down into its building blocks. Two new nuclei form, one for each set of chromosomes.

Detailed explanation-3: -Upon mitosis, each daughter cell inherits one pole of the spindle and hence one centrosome consisting of one pair of parental centrioles. This pair splits during early mitosis to seed the formation of the two centrosomes at the opposite poles of the mitotic spindle.

Detailed explanation-4: -Mitosis divides the nucleus into two nuclei, followed by cytokinesis which divides the cytoplasm. Two genetically identical daughter cells result.

Detailed explanation-5: -Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
