Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed. This loss has been linked to heart disease, cancer, Alzheimer’s, and ...

Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes ...

Scientists from the Kavli Institute of Delft University of Technology and the IMP Vienna Biocenter discovered a new property of the molecular motors that shape our chromosomes. While six years ago ...

Robertsonian chromosomes are large chromosomes that form when the long arm of a chromosome breaks and fuses with another chromosome. They are the most common type of chromosome rearrangement in humans ...

The Y chromosome is perhaps the most puzzling part of the human genome. Associated with male development, it is chock-full of repetitive and inverted stretches of DNA, a hurdle that makes it ...

A picture of a mouse MII stage eggs with the location of chromosomes (green) and the distribution of the histone modification H3K4me3 (purple). The team confirmed that H3K4me3 was significantly ...

Forbes contributors publish independent expert analyses and insights. Telomeres, the protective caps at the ends of our chromosomes, act much like the plastic tips of shoelaces, preventing our DNA ...
