Which organelle contains the DNA and provides instructions for cellular functions?

Explanation:
The nucleus acts as the control center of the cell, housing the cell’s DNA organized into chromosomes. This genetic material carries the instructions for making RNA and, ultimately, the proteins that drive most cellular functions, guiding metabolism, growth, and responses to the environment. Mitochondria do contain their own DNA, but only a small subset of genes related to energy production, not the full instructional system for the entire cell. The cytoplasm lacks DNA, and chromosomes are DNA-protein complexes located inside the nucleus rather than separate organelles. So, the nucleus is where the main genetic information resides and where those instructions are coordinated.
