CELL DIVISION AND CANCEROUS CELLS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If mitosis occurred without cytokinesis, the outcome would be ____
A
one cell without a nuclei
B
one cell with 2 identical nuclei
C
2 cells without a nuclei
D
2 cells, each with one nuclei
Explanation: 

Detailed explanation-1: -Cytokinesis is the final step of mitosis in which the contents of the cell (cytoplasm and nuclei) are separated into two distinct, identical daughter cells. Mitosis without cytokinesis results in a cell with more than one nucleus but a connected cytoplasm (syncytium).

Detailed explanation-2: -The cell then splits to form two genetically identical daughter cells, in a process known as cytokinesis. The end of cytokinesis denotes the end of telophase.

Detailed explanation-3: -Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes.

Detailed explanation-4: -Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

Detailed explanation-5: -Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new daughter cells. The nuclei resulting from a mitotic division are genetically identical to the original nucleus.
