Are chromosomes visible when stained?
Yes, chromosomes are visible when stained. Staining helps to enhance the visibility of chromosomes under a microscope by highlighting their distinct features and structures, allowing for easier study and analysis of genetic material.
How do scientists make a karyotype?
Scientists make a karyotype by first collecting cells, typically from blood or amniotic fluid. These cells are then cultured and stained to visualize the chromosomes. The chromosomes are then arranged and photographed to create a karyotype, which shows the number, size, and shape of chromosomes in an individual.
What is a cell with pairs of chromosomes called?
Somatic (diploid) cells have pairs of chromosomes. They have 46 chromosomes, making 23 pairs.Gametes are sex cells (eggs and sperm), they only have 23 chromosomes total. This is because they will combine with another gamete to form an embryo that will have 46.
Cells that do not have pairs of chromosomes?
Cells that do not have pairs of chromosomes are called haploid cells. These cells have only one set of chromosomes, which is half the normal chromosome number for the species. Haploid cells are commonly found in reproductive organs and are involved in sexual reproduction.
What is they name of the special dye you put in cells?
The special dye commonly used to label cells for visualization under a microscope is called a fluorescent dye. It emits light of a specific color when exposed to certain wavelengths of light. These dyes are essential tools in biological research for studying the structure and function of cells.
What is shown is a karyotype?
A karyotype is simply a picture of a person's chromosomes. In order to get this picture, the chromosomes are isolated, stained, and examined under the microscope. Most often, this is done using the chromosomes in the white blood cells. A picture of the chromosomes is taken through the microscope.
What is shown on a karyotype?
A karyotype is simply a picture of a person's chromosomes. In order to get this picture, the chromosomes are isolated, stained, and examined under the microscope. Most often, this is done using the chromosomes in the white blood cells. A picture of the chromosomes is taken through the microscope.
What is inside cells contain DNA and become darkly colored when stained?
chromosomes
What is a cell with pairs of chromosomes called and a cell with no pairs of chromosomes?
A cell with pairs of chromosomes is called a diploid cell, while a cell with no pairs of chromosomes is called a haploid cell. Diploid cells have two sets of chromosomes, one from each parent, while haploid cells have only one set of chromosomes.
Are chromosomes visible when stained?
Yes, chromosomes are visible when stained. Staining helps to enhance the visibility of chromosomes under a microscope by highlighting their distinct features and structures, allowing for easier study and analysis of genetic material.
What is cell with pairs of chromosomes called a cell with no pairs of chromosomes?
A cell with pairs of chromosomes is called a diploid cell, while a cell with no pairs of chromosomes is called a haploid cell. Diploid cells have two sets of chromosomes, one from each parent, while haploid cells have only one set of chromosomes.
What is the medical term meaning stained blood smear is examined to determine the shape of individual red blood cells?
The medical term meaning stained blood smear is examined to determine the shape of individual red blood cells is called a peripheral blood smear. This test is commonly used to assess the morphology and appearance of red blood cells, which can provide valuable information about various blood disorders.

What is Tzanck preparation?
Procedure in which skin cells from a blister are stained and examined under the microscope. Visualization of large skin cells with many.nuclei indicates a positive diagnosis of herpes zoster when combined with results from a physical examination.
Haploid cells are cells that have?
Haploid cells are cells that contain one set of chromosomes, meaning they have half the number of chromosomes as a diploid cell. In humans, haploid cells are sperm and egg cells, which contain 23 chromosomes each. During fertilization, a haploid sperm cell and a haploid egg cell combine to form a diploid zygote with 46 chromosomes.
What is it called when cells are copied with half he number of chromosomes?
Meiosis
The failure of replicated chromosomes to separate is called?
The failure of replicated chromosomes to separate is called nondisjunction. This can lead to an abnormal number of chromosomes in daughter cells during cell division, which can result in genetic disorders such as Down syndrome.
