Pregnancy loss may occur in as many as 25% of all pregnancies. Most of these losses occur in the first trimester, and about ...

As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life. The Y, by contrast, is little more than a nub. Its main purpose is to provide the ...

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 ...

On the other hand, direct observations of living cells demonstrated that individual sections of chromosomes move actively and rapidly. Scientists could not explain how such a dense globule could be so ...

Researchers behind the "Hitler's DNA" documentary say the Nazi dictator likely had Kallmann Syndrome, which can cause ...

Adolf Hitler most likely suffered from the genetic condition Kallmann Syndrome that can manifest itself in undescended ...

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, ...

A new study based on electron microscopy techniques at low temperatures demonstrates that, during mitosis, chromosome DNA is packed in stacked layers of chromatin. The research, published in EMBO ...

Using puzzle pieces from four different DNA analyses, researchers at Karolinska Institutet in Sweden have been able to map three extremely complex chromosome aberrations. This has given families ...

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 ...
