DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.
A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...
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 ...

Those 'DNA knots' weren't knots at all, and the truth is stranger
For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...
It has been claimed that because most of our DNA is active, it must be important, but now human-plant hybrid cells have been ...
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.
The tiny little powerhouses of our cells, the mitochondria, are unique among organelles because they carry their own tiny ...
