DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.

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 diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...

A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...

New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

Changes in genes have been linked to the development of different diseases for a while. However, it's not exactly clear what ...

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 ...

Randomness inside cells can decide whether a cancer returns after chemotherapy or whether an infection survives antibiotics.

It has been claimed that because most of our DNA is active, it must be important, but now human-plant hybrid cells have been ...
