The chromosomes are not 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.
No, chromosomes are not always visible in a cell. They are only visible during cell division when they condense into distinct structures that can be visualized under a microscope. Outside of cell division, chromosomes exist in a less condensed form and are not readily visible.
Chromosomes coil up and become visible during the prophase stage of cell division. This coiling allows the chromosomes to become more condensed and easier to separate during cell division.
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.
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 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.
The chromosomes
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.
Chromosomes.
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.
In a normal eukaryotic cell which is not actively dividing, chromosomes are not visible. The DNA is loosely coiled, dispersed through the nucleoplasm. However, during cell division, the DNA condenses into ordered structures called chromosomes, which are visible under the microscope.
Interphase
Never visible to naked eye.Visible to light microscope during cell division
During Prophase
Chromosomes are visible in the cell nucleus during mitosis and meiosis.
DNA is visible during mitosis (replication) when the chromosomes condense.
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.
