Research suggests core nuclear pore elements shared by all eukaryotes

About 1.7 billion years ago, the cell nucleus burst onto the scene, sequestering the cell’s genetic material inside a protective inner membrane and setting the stage for the evolution of increasingly sophisticated creatures from yeast, say, to plants and human beings. Now research shows that one of the most basic design principles of this new eukaryotic life-form — the gatekeeper to the cell nucleus known as the nuclear pore complex — is largely shared across even the most distantly related eukaryotes.
