How is the X chromosome inactivated?
X chromosome inactivation is a process that occurs in female mammals where one of the X chromosomes in each cell is randomly inactivated. This ensures that both males and females have similar levels of X chromosome gene products. The inactivated X chromosome condenses into a structure called a Barr body.
A human cell with 2 Barr bodies and no Y chromosome is from?
The human cell is most likely from a female individual. Barr bodies are inactivated X chromosomes in females, and the absence of a Y chromosome indicates that the individual does not have male sex chromosomes.
How does the cell adjust to the extra X- chromosome in the female cells?
In female cells with an extra X chromosome (resulting in a condition called Triple X syndrome), the cell can undergo a process called X-inactivation where one of the X chromosomes is inactivated to prevent overexpression of genes. This helps balance gene dosage between XX and XY individuals. However, not all genes on the extra X chromosome may be inactivated, which can lead to variable symptoms in individuals with Triple X syndrome.
What is it called when the inactive X condenses in each cell in to a compact object in the nucleus?
This process is called X-chromosome inactivation, where one of the two X chromosomes in female cells is randomly inactivated to achieve dosage compensation of X-linked genes. The inactivated X chromosome forms a compact structure called a Barr body within the nucleus.
A thread-like body of DNA that is found inside a cell nucleus is called a?
Chromosome

Where in the cell would a chromosome be found?
nucleus:)
How many Barr bodies cell does XXXY has?
A Barr body is an inactivated X chromosome. An XXXY cell would contain 1 Barr Body. Men have no Barr bodies, and women have 1.
A human cell with 2 Barr bodies and no Y chromosome is from?
The human cell is most likely from a female individual. Barr bodies are inactivated X chromosomes in females, and the absence of a Y chromosome indicates that the individual does not have male sex chromosomes.
What cells would you find in a chromosome?
None. Chromosomes are found inside a cell.
What chromosome are found in body cell but not sex cell?
Homologous Chromosomes
How does the cell adjust to the extra X- chromosome in the female cells?
In female cells with an extra X chromosome (resulting in a condition called Triple X syndrome), the cell can undergo a process called X-inactivation where one of the X chromosomes is inactivated to prevent overexpression of genes. This helps balance gene dosage between XX and XY individuals. However, not all genes on the extra X chromosome may be inactivated, which can lead to variable symptoms in individuals with Triple X syndrome.
Wher is DNA found?
Within a cell's chromosome.
Where a chromosome is found?
In the nucleus of each cell in the body.
What is the Number of Barr bodies inside cheek cell of male with Klinefelter's Syndrome?
A male with Klinefelter's Syndrome (XXY genotype) would have two Barr bodies in each cheek cell, as they have an extra X chromosome. This extra X chromosome forms Barr bodies inactivated during embryonic development, leading to the presence of two Barr bodies in cells with two X chromosomes.
What is it called when the inactive X condenses in each cell in to a compact object in the nucleus?
This process is called X-chromosome inactivation, where one of the two X chromosomes in female cells is randomly inactivated to achieve dosage compensation of X-linked genes. The inactivated X chromosome forms a compact structure called a Barr body within the nucleus.
Where is a barr body found?
A Barr body is the inactivated X chromosome that is usually found in the nuclei of female somatic cells. It can also occur in males when there is an abnormality and the male is XXY instead of the normal XY, a condition known as Klinefelter's syndrome. In this case, the male somatic cells would also contain a Barr body. --- The Barr body is the highly-condensed chromatin structure taken up by an inctivated X chromosome. The number of Barr bodies equal the number of inactive chromosomes.
