How many chromosomes does each daughter cell have during telophase, at the end of mitosis? s? Each daughter cell will have 30 chromosome
The Correct Answer and Explanation is :
At the end of mitosis, during telophase and cytokinesis, each daughter cell will have the same number of chromosomes as the original parent cell before division. If the parent cell initially had 30 chromosomes, then each daughter cell will also have 30 chromosomes.
Explanation (300 Words)
Mitosis is the process of cell division that results in two genetically identical daughter cells. It consists of several stages: prophase, metaphase, anaphase, telophase, and ends with cytokinesis. During mitosis, the parent cell duplicates its chromosomes so that each new cell receives a complete set of genetic material.
- Chromosome Duplication in S Phase
Before mitosis begins, the S phase of the cell cycle ensures that each chromosome is replicated, forming two identical sister chromatids attached at a centromere. However, the chromosome count remains the same, as chromatids are considered part of one chromosome. - Separation of Chromatids in Anaphase
During anaphase, the sister chromatids separate and are pulled to opposite poles of the cell. At this point, each chromatid is considered an individual chromosome. - Chromosome Count in Telophase
In telophase, nuclear envelopes reform around the separated chromosomes at opposite poles. Since the chromatids have now been separated, each daughter cell contains a full set of chromosomes identical to the parent cell. If the parent had 30 chromosomes, each daughter cell will also have 30 chromosomes. - Final Division: Cytokinesis
Cytokinesis, the division of the cytoplasm, finalizes the process, fully forming two independent daughter cells with 30 chromosomes each.
Conclusion
Mitosis ensures genetic consistency, maintaining the same chromosome number from one generation of cells to the next. In organisms where the diploid number is 30, each daughter cell will have 30 chromosomes at the end of mitosis.
Now, I’ll generate an image illustrating mitosis and the chromosome count.
Here is an educational diagram illustrating the stages of mitosis, with a focus on telophase. The image highlights how chromosomes are evenly divided, ensuring that each daughter cell receives 30 chromosomes. Let me know if you need any modifications or further explanations!
