Chromosome Number and DNA Content during Mitotic Division
Metaphase is a stage in mitosis where the chromosomes align along the equatorial plane of the cell. Anaphase follows metaphase and is characterized by the separation of sister chromatids. To determine the chromosome number (N) and DNA content (C) during these stages, we need to consider the process of mitotic division and the behavior of chromosomes.
Mitotic Division:
Mitotic division is a type of cell division that occurs in somatic cells, resulting in the formation of two identical daughter cells. It consists of several stages: prophase, metaphase, anaphase, and telophase.
During prophase, the chromatin condenses into visible chromosomes, and the nuclear membrane disintegrates. Each chromosome consists of two identical sister chromatids held together at a region called the centromere.
In metaphase, the chromosomes align along the equatorial plane of the cell, forming a metaphase plate. This alignment is crucial for the proper segregation of chromosomes during anaphase.
Anaphase is characterized by the separation of sister chromatids. The microtubules of the spindle fibers shorten, pulling the sister chromatids towards opposite poles of the cell.
During telophase, the nuclear membrane reforms around the separated chromatids, and cytokinesis occurs, resulting in the formation of two daughter cells.
Chromosome Number (N) during Metaphase:
During metaphase, the chromosome number (N) remains the same as the original cell. In this case, the cell initially had 32 chromosomes. Therefore, the chromosome number during metaphase would also be 32.
DNA Content (C) during Anaphase:
The DNA content (C) in a cell is determined by the amount of DNA present in its chromosomes. Each chromosome contains a single molecule of DNA.
During anaphase, the sister chromatids separate and move towards opposite poles of the cell. As a result, each newly formed daughter cell receives an equal number of chromatids.
Since the chromatids are identical copies of each other, the DNA content in each daughter cell remains the same as the original cell. Therefore, the DNA content during anaphase would also be 32.
Conclusion:
Based on the information provided, the correct answer would be A) N=32, C=32. During metaphase, the chromosome number remains the same as the original cell, which is 32. During anaphase, the DNA content also remains the same as the original cell, which is 32.

A cell has 32 chromosomes. If undergoes mitotic division what will be ...
Answer should be B probably as till metaphase, the chromosome don't split.. they're same in number as before (32) while when anaphase starts, they split thus giving 64 chromosomes
