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 ...

A UCSF study reveals that maternal X chromosome expression may accelerate brain aging and cognitive decline. Female mice with ...

The X contains more genes related to brain function than does any other chromosome. “The X chromosome may be a treasure trove of genes that influence cognition, and these could be therapeutic targets, ...

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

while males had one X and one Y. Y chromosomes are hard to sequence because they contain a lot of repetitive "junk" DNA, so ...

whereas most eukaryotes have one or more linear chromosomes, which often appear as X-shaped structures . At different times during the life cycle of a cell, the DNA that makes up the cell's ...

New research shows that female mice expressing only a maternal X chromosome experience faster brain aging and cognitive ...

Females carry two X chromosomes, after inheriting one from each parent. In order to stop serious problems from arising, cells ...

Chromosomes are often observed and depicted as X-shaped structures. DNA takes this form following DNA replication during the process of cell division when the two replicated chromosomes ...

Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact ...

A study conducted by a research team at the Crick Institute identified important genes on the Y chromosome that regulate ...
