Nuclear Pores

Nuclear pores are tiny gateways embedded in the nuclear envelope, which surrounds the nucleus of a cell. They regulate the exchange of materials between the nucleus and the cytoplasm, allowing proteins, RNA, and other molecules to pass in and out. These pores are highly selective, ensuring that essential molecules enter the nucleus or exit it while blocking unwanted substances. They are made up of multiple protein complexes forming a dynamic structure that maintains cellular function and communication, functioning like security checkpoints controlling traffic between the nucleus and the rest of the cell.
