CELL DIVISION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Mitosis and meiosis are processes by which animal and plant cells divide. Which statement best describes a difference between mitosis and meiosis?
A
Meiosis is a multi-step process.
B
Mitosis occurs only in eukaryotic cells.
C
Meiosis is used in the repair of an organism.
D
Mitosis produces genetically identical daughter cells
Explanation: 

Detailed explanation-1: -Expert-Verified Answer. The best and most correct answer among the choices provided by the question is the fourth choice. The main difference between mitosis and meiosis is that mitosis produces genetically identical daughter cells.

Detailed explanation-2: -D. Correct-Cells produced through mitosis contain DNA identical to the parent cells, whereas meiosis produces cells that are haploid and often genetically different.

Detailed explanation-3: -Expert-Verified Answer. Explanation: Cells in mitosis go through the PMAT stages twice to produce diploid cells while cells in meiosis go through PMAT stages once to produce haploid cells Cells in mitosis and meiosis go through the PMAT stages twice to produce haploid cells.

Detailed explanation-4: -Mitosis produces two genetically identical “daughter” cells from a single “parent” cell, whereas meiosis produces cells that are genetically unique from the parent and contain only half as much DNA. Most cells in the body regularly go through mitosis, but some do so more often than others.

Detailed explanation-5: -Mitosis results in two nuclei that are identical to the original nucleus. Meiosis, on the other hand, results in four nuclei, each having half the number of chromosomes of the original cell. In animals, meiosis only occurs in the cells that give rise to the sex cells (gametes), i.e., the egg and the sperm.
