During Which Three Phases Are Individual Chromosomes No Longer Visible?

G1, S, and G2 make up interphase, when ordinary light microscopy does not distinguish individual condensed chromosomes.

Question

Choose the three cell-cycle stages in which ordinary light microscopy does not resolve separate, condensed chromosomes. Select one group.A. The final stage of mitosis (telophase), cytoplasmic division (cytokinesis), and the resting state G0B. The first gap (G1), DNA synthesis (S), and the second gap (G2)C. DNA synthesis (S), the mitotic phase (M), and the resting state G0D. The first three named stages of mitosis: prophase, metaphase, and anaphase

Evidence boundary

This is an adapted version of Pearson cell-biology asset 14081560, preserving its four option groups and their order. It uses the G1/S/G2 interpretation and does not answer the different Gizmo worksheet version. Chromosome visibility depends on preparation, staining, and imaging method; decondensation is gradual, including during telophase. The answer is not a claim that DNA is absent or that only these stages can contain uncondensed chromatin.
