Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
the stage of mitosis in which the nuclear membrane reforms and the nucleus divides
A
metaphase
B
prophase
C
telophase
D
anaphase
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. 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-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: -Anaphase I begins when homologous chromosomes separate. The nuclear envelope reforms and nucleoli reappear.

Detailed explanation-5: -Answer and Explanation: During prophase in mitosis is when the nuclear envelope and nucleoli dissolve.
