Question
During ______________________, the chromosomes first become visible.
Group of answer choices
- interphase
- prophase
- metaphase
- anaphase
Solution
The correct answer is prophase.
Explanation:
During prophase, which is the first stage of mitosis, the chromosomes condense and become visible under a light microscope. The chromatin fibers, which are in a less condensed form during interphase, coil and shorten to form distinct chromosomes. Each chromosome consists of two sister chromatids joined at the centromere. The nuclear envelope breaks down, and the spindle apparatus begins to form, aiding in the subsequent alignment and separation of the chromosomes.
To summarize, prophase is characterized by the visibility of chromosomes, a key feature noted in the process of cell division.
