CELL DAMAGE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During cytokinesis, the cell ____
A
copies the DNA
B
splits the nucleus
C
forms chromosomes
D
divides into two cells
Explanation: 

Detailed explanation-1: -Cell division ends with the physical separation of the two daughter cells, a process known as cytokinesis. This final event ensures that nuclear and cytoplasmic contents are accurately partitioned between the two nascent cells.

Detailed explanation-2: -Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells.

Detailed explanation-3: -Cytokinesis is the physical process that finally splits the parent cell into two identical daughter cells. During cytokinesis, the cell membrane pinches in at the cell equator, forming a cleft called the cleavage furrow.

Detailed explanation-4: -While the process of cytokinesis results in the physical partition of a mother cell into two daughter cells, the approach to cell division differs between several model organisms. (A) Higher plants, after separating the nuclei, use microtubules to deliver Golgi-derived vesicles to the equatorial region.

Detailed explanation-5: -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.
