CELL DAMAGE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A human cell has 46 chromosomes before mitotic division. How many chromosomes will the daughter cells after mitosis.
A
12
B
23
C
46
D
92
Explanation: 

Detailed explanation-1: -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-2: -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-3: -When the cell divides, the copies are pulled apart, and each new cell gets one identical copy of each chromosome. This type of cell division is called mitosis, and it produces cells with a total of 46 chromosomes.

Detailed explanation-4: -A cell having 46 chromosomes will form daughter cells having chromosomes after meiosis. No worries!
