Answer:
Introduction:
The cell cycle consists of several stages, and each stage has its own significance. Prophase is the first stage of the cell cycle. During prophase, the chromatin condenses into discrete chromosomes, and the nuclear envelope breaks down. The spindle fibers also start to form. Anaphase is the stage of the cell cycle where the sister chromatids separate and move towards opposite poles of the cell.
Given:
- Prophase:
- 100 units of DNA
- 50 chromosomes
- Anaphase: ?
Solution:
During anaphase, the sister chromatids separate, and each chromatid is considered a separate chromosome. Therefore, the number of chromosomes in anaphase will be double the number of chromosomes in prophase. However, the total amount of DNA remains the same throughout the cell cycle.
Calculation:
- Prophase:
- 100 units of DNA
- 50 chromosomes
- Anaphase:
- Total amount of DNA = 100 units
- Number of chromosomes = 50 x 2 = 100 chromosomes
Conclusion:
Therefore, the correct answer is option 3, 100 DNA and 100 chromosomes in anaphase of the cell cycle.

IN Anaphase of cell division metaphase plate is split and form two daughter chromatids move towards opposite poles ...so the amount of DNA and Number of chromosomes are half of the initial amount ...
