검증된 단계별 안내1
Recall the stages of mitosis: prophase, metaphase, anaphase, and telophase, each with distinct cellular events.
Understand that chromosome condensation is the process where chromatin fibers become tightly coiled and visible under a light microscope.
Identify that chromosome condensation begins early in mitosis, making chromosomes visible as distinct structures.
Recognize that this condensation and visibility first occur during prophase, the initial phase of mitosis.
Confirm that in later phases (metaphase, anaphase, telophase), chromosomes are already condensed and visible, so the first appearance is in prophase.
