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 ...

For a long time, so-called satellite DNA was considered largely worthless. Now, ETH Zurich researchers have shown in fruit ...

Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a discovery that could ...

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 ...

When chromosomes shatter, they sometimes reform into giant circular monsters. These beasts gobble up cancer genes, incorporate them into their DNA, and seed aggressive tumours. The discovery is an ...

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, ...

For palaeontologists, DNA is infuriatingly fragile. Its long chains begin to break apart shortly after death, destroying valuable information about the deceased parent organism. Unlike bones, ...

A new analysis of ancient DNA has found that Neanderthal genomes contain 62 percent more ancestry from anatomically modern humans on their X chromosomes than on the rest of their chromosomes. The ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study ...
