X inactivation is the dosage compensation mechanism in mammals whereby during embryogenesis of females a single X-chromosome is genetically silenced. Although most genes are subject to X ...

Particularly, researchers have found that genes on chromosome 9 are associated with anxiety. But your experiences within your environment — including family upbringing and major life events ...

The silencing of the one X chromosome in XX cells is mediated by XIST, a long noncoding RNA that is randomly transcribed from only one X early in development. It coats the DNA and shuts down gene ...

Researchers at the Francis Crick Institute studying male mice engineered with different Y chromosome deletions have uncovered which genes on the mouse Y chromosome regulate the development of ...

Researchers at the Crick 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 ...

Chromosomes contain hundreds to thousands of genes, which are sections of DNA located at specific points on a chromosome. The Y chromosome is an exception, only containing a few dozen genes.

The cell's nucleus contains chromosomes. These are long threads of DNA, which are made up of many genes. Humans have around 25,000 genes across their 23 pairs of chromosomes.
