MITOSIS AND MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which phase of mitosis are two new nuclei formed?
A
prophase
B
metaphase
C
anaphase
D
telophase
Explanation: 

Detailed explanation-1: -During the completion of mitosis (telophase), two new nuclei form around the separated sets of daughter chromosomes (see Figure 8.29).

Detailed explanation-2: -During the mitotic phase, a cell will undergo mitosis to form two new nuclei and then divide to form two new individual cells during cytokinesis. Mitosis is the process of dividing the duplicated DNA of a cell into two new nuclei.

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: -In telophase, 2 daughter nuclei form. The nuclear envelope beings to reappear. DNA begins to de-condense while spindle microtubules begin to depolymerize. Mitosis, the division of one nucleus into 2, is now complete.

Detailed explanation-5: -M phase. During the mitotic (M) phase, the cell divides its copied DNA and cytoplasm to make two new cells.
