A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

DNA might be too small to see with the unaided eye, but it packs our cells in shocking quantities: More than six and a half feet of DNA lies within every cellular nucleus. It squeezes into such a ...

An illustration of multicolored tangle of threads within a small black sphere. A 3D illustration shows DNA packaged into the nucleus, scientists with the 4D Nucleome project are now building accurate ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

Fragments of DNA from long-extinct human relatives still circulate in modern genomes, and in some cases they do more than ...
