TY - CHAP M1 - Book, Section TI - The Nucleus A1 - Mescher, Anthony L. PY - 2024 T2 - Junqueira's Basic Histology: Text and Atlas, 17th Edition AB - Containing the code for all of a cell’s enzymes and other proteins, the nucleus is the command center of the cell. The nucleus also holds the molecular machinery to replicate the DNA and to synthesize and process all types of RNA. Between cell divisions pore complexes in the membrane enclosing the nucleus regulate macromolecular transfer between the nuclear and cytoplasmic compartments. Mature RNA molecules pass into the cytoplasm for their roles in protein synthesis, while proteins needed for nuclear activities are imported there from the cytoplasm. Restricting protein synthesis to the cytoplasm helps ensure that newly made RNA molecules do not become involved in translation before processing is completed.
