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.

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 ...

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

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 ...

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 ...

In females with two X chromosomes – one inherited from each parent – one of the two X chromosomes is randomly silenced in every cell through a process called X-inactivation. When this process occurs, ...

The image is a time projection of mitochondria (in the cytoplasm, grey) and chromosomes (center of the cell, orange) during anaphase showing a flow pattern with vortexes. The flow pattern is aligned ...

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 ...

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 ...
