Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

Cancer’s most catastrophic DNA damage has long looked like a crime scene without a culprit, with chromosomes shattered and ...

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 ...

A new study conducted in roundworms finds that a common plastic ingredient causes breaks in DNA strands, resulting in egg cells with the wrong number of chromosomes. A new study conducted in ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

Deep in coastal mangroves and even inside our own mouths, biologists are finding that DNA does not always sit in a simple loop at the cell’s center. A giant microbe called Thiovulum imperiosus has now ...

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 ...

A new study conducted in roundworms finds that a common plastic ingredient causes breaks in DNA strands, resulting in egg cells with the wrong number of chromosomes. Monica Colaiácovo of Harvard ...

Non-Africans carry around 2% Neanderthal DNA in their genomes — yet there's one chromosome where DNA from our ancient cousins is nowhere to be found. When you purchase through links on our site, we ...

Robertsonian chromosomes are large chromosomes that form when the long arm of a chromosome breaks and fuses with another chromosome. They are the most common type of chromosome rearrangement in humans ...
