Nucleolus

A structure located within the cell nucleus, primarily involved in the synthesis and assembly of ribosomes, essential components for protein production.

Nuclear Envelope

The double-membrane structure that encloses the nucleus of a eukaryotic cell, separating the nucleus from the cytoplasm and containing nuclear pores for transport.

Nuclear Pores

Openings in the nuclear envelope that allow the passage of ions, molecules, and RNA between the nucleus and the cytoplasm.
