Neurons lack the flexibility to copy their DNA, so that they’re consistently working to restore harm to their genome. Now, a brand new research by Salk scientists finds that these repairs should not random, however as a substitute concentrate on defending sure genetic “scorching spots” that seem to play a essential function in neural identification and performance.

The findings, printed within the April 2, 2021, concern of Science, give novel insights into the genetic constructions concerned in
