Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which part of the mitosis is the end phase when the spindle fibers break down?
A
Anaphase
B
Telophase
C
Interphase
D
Prophase
Explanation: 

Detailed explanation-1: -Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.

Detailed explanation-2: -Telophase. During telophase, the chromosomes begin to uncoil and form chromatin. This prepares the genetic material for directing the metabolic activities of the new cells. The spindle also breaks down, and new nuclear membranes (nuclear envelope) form.

Detailed explanation-3: -Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.

Detailed explanation-4: -Telophase. The final stage of mitosis, and a reversal of many of the processes observed during prophase. The nuclear membrane reforms around the chromosomes grouped at either pole of the cell, the chromosomes uncoil and become diffuse, and the spindle fibres disappear.

Detailed explanation-5: -During anaphase, the microtubules begin to shorten, pulling the chromosomes apart into their individual chromatids. They move toward each centrosome, or as they are referred to now, spindle pole. Once we hit the telophase, the microtubules that are attached to the chromatids begin to disappear.
