Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health. But evidence has ...

A new article analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study demonstrates that the multilaminar ...

The human genetic blueprint is deceptively simple. Our genes are tightly wound into 46 X-shaped structures called chromosomes. Crafted by evolution, they carry DNA and replicate when cells divide, ...

When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells.

Neanderthals, the closest cousins of modern humans, lived in parts of Europe and Asia until their extinction some 30,000 years ago. Genetic studies are revealing ever more about the links between ...

Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

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 ...

Recently, the research team led by Prof. Junjiu Huang from Sun Yat-sen University, in collaboration with Prof. Fenghua Liu’s team at Guangdong Women and Children Hospital, published a study titled ...

Chromosomal instability is a phenomenon characterized by rapid changes in the number and structure of chromosomes during cell division. It is very common in solid tumors and it is linked to the ...
