Real image of DNA molecules being copied in human cells, visualized by immunofluorescence microscopy. The yellow arrows mark where replication begins, and the white arrows indicate the direction in ...

Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random, unpredictable DNA copying "mistakes" account for nearly two-thirds of the mutations that ...

Every time a cell divides, its DNA is duplicated so that the two daughter cells have the same genetic material as their parent. This means that millions of times a day a biochemical wonder takes place ...

Comparative genomic hybridization (CGH) was developed to identify pathogenic DNA copy-number changes (e.g., duplications, deletions) on a genome-wide scale, and to map these changes to genomic ...

Scientists have found that non-coding ‘junk’ DNA, far from being harmless and inert, could potentially contribute to the development of cancer. Their study has shown how non-coding DNA can get in the ...

Artificial intelligence has just redrawn the map of our genome’s control room, revealing hundreds of thousands of tiny DNA ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...
