Question
In mitosis, how do the chromosomes in daughter cells compare with those in the parent cell?
The correct answer is
Daughter cells have the same number of chromosomes as the parent cell.
Mitosis: Chromosome Number Consistency
Mitosis is a fundamental process of cell division where a single parent cell divides to produce two genetically identical daughter cells.
The primary goal of mitosis is to ensure that each new daughter cell receives an exact copy of the parent cell's genetic material.
Chromosome Comparison in Mitosis
- During the cell cycle, specifically during the S phase, the DNA (and thus the chromosomes) in the parent cell is replicated.
- In mitosis, these replicated chromosomes are carefully separated, with one complete set distributed to each new daughter cell.
- Consequently, the daughter cells have the same number and type of chromosomes as the original parent cell. This maintains the diploid (2n) or haploid (n) state of the cell line.
Therefore, the chromosomes in the daughter cells are identical in number to those in the parent cell.
