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 ...

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

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

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

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 ...

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