In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years ...

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 ...

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 sperm ...

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 ...

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 ...

Higher yields, greater resilience to climatic changes or diseases—the demands on crop plants are constantly growing. To address these challenges, researchers of Karlsruhe Institute of Technology (KIT) ...

Bacterial DNA much more twisted than originally thought. Akin to the well-mixed colors in Jackson Pollock’s ‘Convergence’, the findings reported by transposable phage Mu highlight that all loci in the ...

This is a preview. Log in through your library . Abstract To obtain a better understanding of the relationship between metaphase chromosome banding patterns and genome organization, attention was ...

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't ...

For a person with two X chromosomes, full expression of the genes on both could mean a disastrous double dose of their protein products, interfering with the delicate balance of protein expression and ...
