Scientists discover hidden DNA scaffolding that forms before genes activate, revealing life’s blueprint is built before it begins.

Getting DNA into a living cell sounds simple, until you remember the cell’s outer membrane acts like a guarded wall. DNA strands carry a negative charge, and they do not cross that wall easily.
