Chromosomes are visible during prophase. Chromosomes are only visible in cells during the cell division because the DNA and protein that the chromosomes are made of are spread throughout the nucleus.

Chromosomes are visible during cell division (mitosis and meiosis) when they condense and become tightly coiled. This allows them to be easily distinguished under a microscope. In non-dividing cells, chromosomes are usually not visible as distinct structures.
Chromosomes are not visible during the interphase stage of the cell cycle when they are in their less condensed form. Additionally, chromosomes may not be visible if the cell is not actively dividing or if they are not stained for observation under a microscope.
Chromosomes are clearly visible only when a cell is undergoing cell division, specifically during the metaphase stage of mitosis or meiosis. During this stage, chromosomes condense and become visible under a microscope.
during prophase
Chromosomes are visible in the cell nucleus during mitosis and meiosis.
During prophase, chromosomes condense and become more visible because they coil tightly to form shorter and thicker structures. This condensation helps prevent tangling and facilitates the movement of chromosomes during cell division. Additionally, the condensation of chromosomes helps ensure that each daughter cell will receive the correct number and type of chromosomes.
