What else can I help you with?
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.
How is a karyotype prepared and what is the process involved in creating it?
A karyotype is prepared by taking a sample of cells, usually from blood or amniotic fluid, and growing them in a lab. The cells are then stained to make the chromosomes visible under a microscope. The chromosomes are arranged and photographed to create a karyotype, which shows the number, size, and shape of the chromosomes in an individual's cells. This helps to identify any genetic abnormalities or disorders.
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.
Who examined stained cells and found rods he called chromosomes?
The scientist who examined stained cells and found rods he called chromosomes was Theodor Boveri. He made important contributions to the understanding of chromosomal behavior during cell division.
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.
What would you expect to see inside the stained cells nucleus?
It would be the color you stained.
When chromosomes are visible?
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.

What do the bands on chromosomes signify?
The bands on chromosomes are regions of condensed DNA that are stained differently to create a visible pattern. These bands help scientists identify and locate specific genes on the chromosomes. The patterns of bands can also reveal genetic abnormalities or structural rearrangements in the chromosomes.
What is inside cells contain DNA and become darkly colored when stained?
chromosomes

When does a chromosome first become visible in mitosis?
During the Prophase. :)Chromosomes become highly condensed.They are visible to light microscope,not naked eye
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.
