In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in ...

Scientists show how stem cells process DNA with speed and precision, revealing principles that could lead to programmable DNA ...

“While the rest of the genome shuffles between the maternal and paternal origins, centromeres are inherited intact: one from ...

To make the behavior of DNA understandable and predictable, the researchers combine lab experiments with computer simulations. (Photo: Lennart ...

Every cell in a body contains the same genetic sequence, yet each cell expresses only a subset of those genes. These cell-specific gene expression patterns, which ensure that a brain cell is different ...

The rigors of space travel could accelerate changes in the human body usually associated with aging. According to a new study of human tissues sent into low-Earth orbit, time in space reduces cell ...
