New research shows the X chromosome influences disease risk, immunity and drug response beyond its role in sex.

Researchers are gaining a new appreciation for the genes on the X and Y chromosomes and how they shape sex differences in ...

DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes.

Researchers at the University of California San Diego (UCSD) have demonstrated an intriguing new variation on the CRISPR gene-editing system, which involves fixing a mutation on one chromosome by ...

Unique sex chromosomes occur in species from humans to birds, worms, and flies. An unequal pair of sex chromosomes, each carrying a different complement of genes, requires specific efforts to regulate ...

Is the end of men near? Scientists warn the Y chromosome, key to male identity, is shrinking fast after 166 million years of ...

The X chromosome is associated with important measures of the brain in aging and Alzheimer's disease (AD) in sex-specific ways, new research suggests. In a cohort study, differential gene expression ...

Humans have 23 pairs of chromosomes, including a pair of sex chromosomes (typically XX for females, and XY for males). Chromosomes contain hundreds to thousands of genes, which are sections of DNA ...

Two new studies of the evolutionary history of the Y chromosome show that, contrary to popular (if not scientific) belief, the male is not at risk of dying out. The Y chromosome which, among other ...
