Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...

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 ...

Twenty years after the Human Genome Project was declared complete, the Y chromosome has been fully sequenced for the first time. Most people have 22 pairs of chromosomes plus two sex chromosomes – ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature. Subscribe to our newsletter for the latest sci-tech news updates.

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, ...

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

In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years later in a commentary, "is running out of time." The male-determining sex ...

TORONTO - Scientists at The Hospital for Sick Children (HSC) have compiled the complete DNA sequence of human chromosome 7 and decoded nearly all of the genes on this medically important portion of ...

Genes do not exist in isolation. Like beads on a string, they sit next to each other on long DNA molecules called chromosomes. So far, little has been known about how the position of a gene on a ...
