Multiple Choice
During which phase of the cell cycle do chromosomes first become visibly condensed under a light microscope?
A
S phase of interphase
B
Prophase of mitosis
C
G1 phase of interphase
D
Cytokinesis (after telophase)
Verified step by step guidance1
Recall the stages of the cell cycle: G1 phase, S phase, G2 phase (all part of interphase), followed by mitosis (prophase, metaphase, anaphase, telophase), and finally cytokinesis.
Understand that during interphase (G1, S, G2), the chromatin is generally in a less condensed, more relaxed state, allowing for DNA replication and gene expression.
Recognize that chromosome condensation is a key event that makes chromosomes visible under a light microscope, and this condensation begins at the start of mitosis.
Identify that prophase is the first phase of mitosis where chromosomes start to condense and become visible as distinct structures.
Conclude that chromosomes first become visibly condensed during prophase of mitosis, not during any phase of interphase or cytokinesis.
