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.

When are Chromosomes not visible?
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?
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.
What is it when chromosomes are first visible?
during prophase
When choromosomes are visible in the nucleus?
Chromosomes are visible in the cell nucleus during mitosis and meiosis.
Why do chromosomes become more visible during prophase?
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.

What can you infer about a cell whose chromosomes are not visible?
If chromosomes are not visible, it could mean that the cell is not undergoing cell division, as chromosomes are condensed and visible during that process. Alternatively, it could indicate that the cell is in a phase where the chromosomes are not easily distinguishable, such as during interphase. Further investigation or staining techniques may be needed to visualize the chromosomes.
At what stage in meiosis are the chromosomes visible?
Chromosomes are visible during the prophase stage of meiosis, specifically during prophase I. This is when the chromosomes condense and become visible under a microscope.
What stage does rod-shaped chromosomes are first visible?
Rod-shaped chromosomes are first visible during prophase of mitosis. At this stage, the chromosomes condense and become visible as rod-shaped structures in preparation for cell division.
When does a chromosome first become visible in mitosis?
Chromosomes become visible in mitosis during prophase when they condense and become tightly coiled. Prior to prophase, chromosomes are not visible as distinct structures.
Chromosomes are clearly visible only when a cell is?
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.
Name the phase of cell division when duplicated chromosomes first appear?
The phase of cell division when duplicated chromosomes first appear is called the prophase. In prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down, allowing the chromosomes to be more clearly visible.
What is it when chromosomes are first visible?
during prophase
When during the cell cycle are chromotomes visible?
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.
Are chromosomes visible during pro-phase?
yes they are now visible during prophase
When choromosomes are visible in the nucleus?
Chromosomes are visible in the cell nucleus during mitosis and meiosis.
Why do chromosomes become more visible during prophase?
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.
