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 ...

X-chromosome inactivation varies across different areas of brains. Here, fluorescent imaging data from a mouse reveal where the father’s X chromosome is most active (white) and least active (blue). A ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

About 80% of orange cats are males, including the four orange cats owned by the Short Wave team: Zuko, Benny, Tang and Dorito. Scientists have long suspected that their orange color was a sex-linked ...

Researchers discover unexpected patterns in mutation risks across individuals, uncovering 13 distinct genomic patterns. The study provides crucial insights into cancer evolution, identifying the genes ...

Researchers have discovered how orange cats got their coats — and why so many of them are male. The coat color comes from a genetic mutation on the X chromosome of orange, calico and tortoiseshell ...

A novel genome editing technique, NICER, is based on the creation of multiple nicks in single DNA strands by nickase. The method can correct heterozygous mutations using two mechanisms: multiple nicks ...

An international study has identified more than 50 genes on the X chromosome in which mutations may cause poor sperm production. Nearly half of all men with low or zero sperm count have no medical ...
