Repetitive DNA near chromosome centers forms a unique barcode for partner recognition. This barcode guides chromosomes to ...

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

Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development ...

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 ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

Scientists found centromere DNA sitting at telomeres in ALT cancers, a merger of chromosome regions once thought impossible.` ...

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 ...

Researchers used a new method to investigate past interbreeding with Homo sapiens that doesn't require ancient DNA. The technique identified areas of living humans' genomes that came from unknown ...

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 ...

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 ...
