Chromosome duplication prior to mitosis ensures that each daughter cell receives an identical set of genetic information. This is crucial for maintaining the correct number of chromosomes in each cell and for enabling accurate cell division. It also helps in preventing mutations and ensuring genetic stability in the daughter cells.
duplication, separation, and cytokinesis
The nucleus of the cell contains the genetic material, including chromosomes, and it plays a critical role in controlling replication prior to cell division. Within the nucleus, specialized structures such as the nucleolus and proteins involved in DNA replication help regulate the process of chromosome duplication.
During cell division, the chromosome number remains constant. In mitosis, each daughter cell receives an identical set of chromosomes to the parent cell. In meiosis, the chromosome number is halved to produce gametes with half the number of chromosomes as the parent cell.
This is known as a chromosomal duplication, which involves the replication of a segment of a chromosome resulting in an extra copy. Duplication can lead to genetic disorders or variations in an individual's traits.
MITOSIS
The G2 phase is immediately preceded by the S ( DNA synthesis for chromosome duplication) phase, and is followed by the M (mitosis, or cell division) stage.
Chromosome duplication prior to mitosis ensures that each daughter cell receives an identical set of genetic information. This is crucial for maintaining the correct number of chromosomes in each cell and for enabling accurate cell division. It also helps in preventing mutations and ensuring genetic stability in the daughter cells.
The type of cell division that is known as the duplication division is called DNA replication. During DNA replication, the genetic material is duplicated to maintain the genetic information in the daughter cells during cell division.

DNA duplication occurs during the S phase of the cell cycle. This is when the DNA in the cell is replicated in preparation for cell division.
Mitosis is cell division in which the chromosome number stays the same. Although at some points throughout the cell cycle, chromosomes may consist of two sister chromatids
