Hint: A parent cell splits into two or more daughter cells in the process of cell division. Normally, cell division happens as part of a broader cell cycle. In eukaryotes, there are two forms of cell division: vegetative cell division (mitosis), in which each daughter cell is genetically identical to the parent cell, and reproductive cell division (haploid gametes), in which the number of chromosomes in the daughter cells is decreased by half (meiosis).
Complete answer:
Mitosis is the phase of the cell cycle in which a cell's nucleus is split into two nuclei, each with an equal quantity of genetic material. After the nucleus has been separated, it follows the G2 phase and is followed by cytoplasmic division.
Mitosis is required for cell development and the replacement of worn-out cells. Abnormalities in mitosis can cause genetic diseases by altering the DNA.
Mitosis Characteristics
Each cell division cycle produces two daughter cells from the parent cell.
The cell is also known as equational cell division since the parent and daughter cells have the same chromosomal number.
Mitosis causes the vegetative portions of the plant, such as the root tip and stem tip, to grow.
This procedure does not include segregation or combining.
The processes that take place during mitosis have been classified into phases.
Interphase
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
During the metaphase stage, the chromosomes are the shortest, most tightly coiled, and most visible. All of the chromosomes are placed on the equatorial plate during metaphase. According to studies, the bigger chromosomes are generally found on the metaphase plate's periphery, whereas the smaller chromosomes are found in the center. This might be because bigger chromosomes travel more slowly than smaller chromosomes, and the distance between the polar centriole and the perimeter of the curved metaphase plate is less than the distance between the polar centriole and the center of the metaphase plate.
Thus, Prophase, metaphase, anaphase, and telophase are the four main stages of mitosis. The form of anaphase chromosomes is determined by the location of their centromeres, which can be V-shaped, metacentric, l-shaped, or submetacentric. Acrocentric or J-shaped, and telocentric or I-shaped.
As a result, option B is the right answer.
Note:
Binary fission is a type of vegetative cell division in which the genetic material of prokaryotes (bacteria and archaea) is divided evenly into two daughter cells. While binary fission is the most common method of prokaryote division, other methods of division, such as budding, have been reported. A single cycle of DNA replication precedes all cell divisions, independent of the organism.
