Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
At the end of the cell cycle, there are two genetically different cells. True or False
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Mitosis divides the nucleus into two nuclei, followed by cytokinesis which divides the cytoplasm. Two genetically identical daughter cells result.

Detailed explanation-2: -In mitosis, the end product is two cells: the original parent cell and a new, genetically identical daughter cell. Meiosis is more complex and goes through additional phases to create four genetically different haploid cells which then have the potential to combine and form a new, genetically diverse diploid offspring.

Detailed explanation-3: -Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell.

Detailed explanation-4: -The nuclei resulting from meiosis are not genetically identical and they contain one chromosome set only. This is half the number of chromosome sets in the original cell, which is diploid.

Detailed explanation-5: -There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division, ” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells.
