Are Barr body projection of extra chromatin on the an X chromosome?
Yes.
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.
An inactive X chromosome which is found in females is referred to as?
X inactive chromosomes are called Legit Durification
Why don't males have Barr bodies?
Both Male and Female have the barr body, but in different chromosones. The above statement is INCORRECT. Barr bodies are formed mainly in females due to females having two X chromosomes while males normally have only one X chromosome (and a Y chromosome). The Barr body is formed from the inactive X chromosome. Males can sometimes be born with a mutation of having too many X chromosomes, in which case Barr Bodies would also be found in those specific males which typically causes Klinefelter's Syndrome.
What is the Number of Barr bodies inside cheek cell of male with Klinefelter's Syndrome?
only one barrbody ts found in kline felters syndrome
A human cell with 2 Barr bodies and no Y chromosome is from?
A female with 3 X chromosomes. (XXX) Two of the X chromosomes will be inactivated, leaving one functional X chromosome, 2 Barr bodies, and no Y chromosome.
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.
Are Barr body projection of extra chromatin on the an X chromosome?
Yes.
How does the cell adjust to the extra X chromosome in female cells?
In females, the extra X chromosome becomes inactive and becomes the Barr body.
How does the cell adjust to the extra X- chromosome in the female cells?
In females, the extra X chromosome becomes inactive and becomes the Barr body.
If the extra x will be Barr bodies why do kline felter males or Turners female have certain problem?
if the extra Xwill be Barr bodies why dp kline felter males or Turnes female have certain problem
Do people with Klinefelter's syndrome have an inactivated X chromosome or a bar body?
People with Klinefert´s syndrome have one barr body. Yes , the number of barr bodies in a cell is always equal to the number of X chromosomes minus one. For example in the XXY chromosome there is one Barr body
Where can barr bodies be found?
BARR BODIES CAN BE SEEN AS A SMALL APPENDAGE ON THE NUCLEOUS OF A POLYMORPHONUCLEAR NEUTROPHIL OF BLOOD CELLS FROM A FEMALE HUMAN. THESE ARE ONE OF THE WHITE CELL TYPES SEEN ON A BLOOD SMEAR DONE ON A CBC. tim goodman clinical lab scientist

An individual with Turner syndrome appears male and has 1 Barr body?
Turner syndrome only affects females. They have only one X sex chromosome and their sex genotype is XO. Since they only have one X sex chromosome, they do not have barr bodies.
An inactive X chromosome which is found in females is referred to as?
X inactive chromosomes are called Legit Durification
Why x-chromosome are also called Barr body?
That is what random X chromosomes do in the female somatic cells. They form Barr bodies. This is a methylated X chromosome that effectively shuts this chromosome down, one per cell in a random manner. This is done by the body because too much protein product is detrimental to organisms.
