Researchers at Linköping University in Sweden made an unexpected discovery while investigating genetically unique women.

Women are born with two X chromosomes and inherit one from each parent. But in every cell of their body, just one X chromosome is needed—so the other is randomly inactivated. Some cells use only a ...

Researchers at Linköping University in Sweden made an unexpected discovery while investigating genetically unique women.

UCSF researchers found that brain cells age more quickly when they rely solely on the X chromosome inherited from a female's ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...

Typically, females carry two X chromosomes in each cell — one from their mom and one from their dad. But a cell needs only one X to be active, so the other is "silenced." This results in females ...

Research from Umeå University paves the way for a quantitative data analysis method to study the cell division process in ...

Women are born with two X chromosomes and inherit one from each parent. But in every cell of their body, just one X chromosome is needed – so the other is randomly inactivated. Some cells use ...

Science has revealed some of the secrets of the X chromosome, but many remain. In humans, female cells contain two X chromosomes (XX) and male cells contain one (XY). In each female cell ...

Researchers have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't produce enough ...

Researchers from the University of California, San Francisco (UCSF) say they have now found that when the brain cells of female mice express only a maternal X chromosome, the animals’ memory and ...
