MITOSIS AND MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What phase of mitosis do you get 2 new nuclei?
A
Prophase
B
Metaphase
C
Anaphase
D
Telophase
Explanation: 

Detailed explanation-1: -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-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 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-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: -Telophase I: The chromosomes are now at opposite ends of the cell and begin to form two distinct chromosome clusters. At this point, nuclear division begins, and the parent cell is divided in half, forming 2 daughter cells.
