Atomic pores, little channels that span the atomic envelope, let substances enter and exit the core. Each pore is lined by a set of proteins, called the atomic pore complex, that control what atoms can go in or out.
The core is spheroid in shape and isolated from the cytoplasm by a layer called the atomic envelope. The atomic envelope confines and ensures a cell's DNA from different atoms that seem incidentally harm its structure or meddled with its handling.
