Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following produces identical nuclei in cells?
A
osmosis
B
mitosis
C
pollination
D
fertilization
Explanation: 

Detailed explanation-1: -Mitosis is the process by which a cell replicates its chromosomes and then segregates them, producing two identical nuclei in preparation for cell division.

Detailed explanation-2: -During mitosis, the chromosomes, which have already duplicated, condense and attach to spindle fibers that pull one copy of each chromosome to opposite sides of the cell. The result is two genetically identical daughter nuclei.

Detailed explanation-3: -In mitosis a cell divides to form two identical daughter cells. It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set. Before mitosis, the chromosomes are copied.

Detailed explanation-4: -Anaphase ensures that each daughter cell receives an identical set of chromosomes, and it is followed by the fifth and final phase of mitosis, known as telophase.

Detailed explanation-5: -Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
