X-chromosome inactivation varies across different areas of brains. Here, fluorescent imaging data from a mouse reveal where the father’s X chromosome is most active (white) and least active (blue). A ...

In female mammals, one of the two X chromosomes is usually inactive and forms the so-called Barr body. The image shows a cell nucleus with the Barr body marked in green. Unlike men, who carry one X ...

Science has revealed some of the secrets of the X chromosome, but many remain. In humans, female cells contain two X ...

Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have identified a mechanism that protects the female brain from genetic diseases. Although one of the two X chromosomes is ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

The cells of female mammals randomly inactivate one X chromosome to keep gene dosage the same as in males. Does it matter which X becomes inactive? Surprisingly, it does, according to new research ...
