Which structure houses the genetic material and acts as the control center of the cell?

The nucleus is the structure that houses genetic material and acts as the control center of the cell. Inside it, DNA is organized into chromosomes, carrying the instructions for making proteins and regulating cellular functions. By controlling which genes are expressed and when, the nucleus directs growth, metabolism, and reproduction. It’s enclosed by a double membrane with nuclear pores that allow communication with the cytoplasm, coordinating activities across the cell. The nucleolus within the nucleus makes ribosomal RNA for ribosome assembly, but it’s the nucleus as a whole that serves as the central command hub. Chromatin is the form of DNA+proteins inside the nucleus that allows packaging and regulation, while ribosomes are the sites of protein synthesis outside the nucleus.
