CELL DAMAGE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A parent cell has 46 chromosomes, How many does each daughter cell have after mitosis?
A
12
B
23
C
46
D
92
Explanation: 

Detailed explanation-1: -At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

Detailed explanation-2: -At this point, nuclear division begins, and the parent cell is divided in half, forming 2 daughter cells. Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes.

Detailed explanation-3: -Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

Detailed explanation-4: -After cytokinesis and karyokinesis, the cell divides into two each daughter cell having the 46 chromosomes forming a total of 92 chromosomes in two cells divided.

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.
