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.
A thread-like body of DNA that is found inside a cell nucleus is called a?
Chromosome
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 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
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.
