Interphase, because during pro phase they become visible so that means in interphase they were not visible.
Chromosomes are no longer visible during the interphase stage of the cell cycle, specifically in the G1, S, and G2 phases, when they are in a relaxed, uncoiled state called chromatin. However, if referring specifically to mitosis, chromosomes become less distinct and start to decondense during telophase, as the nuclear envelope begins to reform. In this stage, they are difficult to distinguish individually.
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.
During Interphase the DNA is not in the form of chromosomes. It is not until Prophase that it condenses and chromosomes become visible.
Chromosomes can be observed during the cell cycle primarily during the stages of mitosis and meiosis, specifically in prophase, metaphase, anaphase, and telophase. In these stages, chromosomes condense and become distinctly visible under a light microscope. Outside of these stages, during interphase, chromosomes are less visible as they are in a more relaxed, uncoiled state known as chromatin. However, they are still present and replicating during the S phase of interphase.
The chromosomes in a cell's nucleus are only visible during the part of the cell cycle known as prophase. Prophase is the stage of mitosis in which chromatin condensation occurs.
During Prophase
Chromosomes are no longer visible during the interphase stage of the cell cycle, specifically in the G1, S, and G2 phases, when they are in a relaxed, uncoiled state called chromatin. However, if referring specifically to mitosis, chromosomes become less distinct and start to decondense during telophase, as the nuclear envelope begins to reform. In this stage, they are difficult to distinguish individually.
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.
During Interphase the DNA is not in the form of chromosomes. It is not until Prophase that it condenses and chromosomes become visible.
Chromosomes are not always visible because they are usually tightly packed and condensed into a structure called chromatin during most phases of the cell cycle. It is only during cell division when chromosomes become highly condensed and visible under a microscope.
Chromosomes are visible during cell division, specifically during mitosis and meiosis. This is when the chromosomes condense and become more distinguishable. In interphase, the chromosomes are less condensed and not easily visible as individual structures.
Sister chromatids are visible during metaphase of mitosis, where they align along the metaphase plate in the center of the cell. This is when the chromosomes are most condensed and easily visible under a microscope.
NO light microscope can not magnify the image to see chromosomes. You can see with fluorescence microscopes to observe them during cell cycle. Light microscope is helpful to check the whole living cell.
Chromosomes can be identified during the cell cycle.
Chromosomes become visible during the prophase stage of the cell cycle, when they condense and can be seen under a microscope as distinct structures. This marks the beginning of cell division.
