A link between our body’s energy levels and a protein that wraps our DNA?
Living organisms need to sense the amount of energy that is available to them and regulate the activity of their genes accordingly. Scientists have made the unexpected finding that a histone protein, which wraps DNA into tight bundles and regulates gene activity, can bind a small molecule produced…
