The core controls and controls the exercises of the cell (e.g., development and digestion system) and carries the qualities, structures that contain the innate data.

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.
