Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Two nuclei are ____ during telophase
A
Synthesized
B
Broken down
C
Either A or B
D
None of the above
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 telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same cell.

Detailed explanation-3: -During mitosis, each duplicated chromosome is evenly divided. Thus, during telophase two identical nuclei are created.

Detailed explanation-4: -During telophase, a nuclear membrane forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm. The chromosomes begin to uncoil, which makes them diffuse and less compact.

Detailed explanation-5: -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.
