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 ...

Changes in genes have been linked to the development of different diseases for a while. However, it's not exactly clear what ...

Transposons, or 'jumping genes' -- DNA segments that can move from one part of the genome to another -- are key to bacterial evolution and the development of antibiotic resistance. Researchers have ...

The findings shed new light on human reproduction and suggest pathways for developing treatments to lower the risk of ...

Some physical traits that differ between sexes are known to be linked to certain single nucleotide polymorphisms (SNPs) in chromosomes other than the X and Y chromosomes, with each SNP representing a ...

The human Y chromosome, responsible for determining male sex, finally has gotten an end-to-end examination. The Y chromosome is the smallest of the human chromosomes. “In the old time, people thought ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature. Chromosomes are thread-like structures that carry a cell's ...

Forget the battle between the sexes. There’s a tinier battle raging within the sexes — at the genetic level. In some species’ sperm, X and Y chromosomes wrestle for dominance, each trying to improve ...
