AI discovery reveals DNA isn’t locked away in cells after all

https://gladstone.org/sites/default/files/styles/news_node/public/news-events/_aaa8147.jpg?itok=Os58rFzW
Every cell in the human body squeezes over six feet of DNA into a miniscule speck invisible to the naked eye—like compressing a whole house into a single sugar cube. In order to fit in a cell and remain organized, DNA is carefully wrapped around spool-like protein clusters called nucleosomes. For decades, the prevailing view held that DNA is coiled so tightly around a nucleosome that it’s ...
