Sex determination at birth is decided on the chromosomes the baby has. A female has two X chromosomes, whereas a male has one X and one Y chromosome. According to Medline Plus, in every cell, humans ...

Researchers from Skoltech, the University of Potsdam, and the Massachusetts Institute of Technology have discovered a ...

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, ...

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 ...

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 ...

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 ...

We investigated the role of initial DNA and chromosome damage in determining the radiosensitivity difference between the variant murine leukemic lymphoblast cell lines L5178Y-S (sensitive) and ...
