Step 1: Concept
Mitosis stages and chromosome visibility
Step 2: Meaning
Understanding the visibility of chromosomes during different phases of mitosis is crucial for cell biology.
Step 3: Analysis
Interphase does not involve active division; instead, it is a period where the cell grows and replicates its DNA. Prophase, metaphase, and anaphase are stages in which chromosomal condensation occurs to make them visible under a light microscope.
Step 4: Conclusion
Chromosomes are not sufficiently condensed during interphase for visibility under a light microscope.
Final Answer: (A)
