Knowledge of DNA repair mechanisms advances with new paper
We humans like to think our DNA is well-protected in the nucleus of each cell. But it's a hard life for the hard-working genetic code.

It's well known that when the DNA in a cell is damaged, the cell responds by activating specific genes that help defend the integrity of its genome. But less well studied is the fact that the cell actually shuts down the ...
