Nuclear RNA export

Nuclear RNA export is the process by which messenger RNA (mRNA) molecules, which are made in the cell's nucleus, are transported out into the cytoplasm. This transfer is essential because the cytoplasm is where proteins are made, using the instructions carried by the mRNA. Specialized proteins recognize and bind to the mRNA, guiding it through nuclear pores—large channels in the nuclear envelope—without damaging the cell's nucleus. This process ensures that genetic information is accurately conveyed from the nucleus to the site of protein synthesis, maintaining proper cell function and response.
