Final answer:
The nucleus is the control center of the cell, housing the cell's DNA, which carries instructions for synthesizing vital molecules.
Step-by-step explanation:
The cellular component that serves as the control center of the cell and contains DNA with instructions for synthesizing vital molecules is D) Nucleus. The nucleus regulates all cell functions and controls the cell's activities by controlling protein synthesis. It does this by housing the cell's DNA, which carries the instructions for protein synthesis. Other cellular components like the Cytoplasm, Mitochondria, and Golgi Apparatus also contribute to the cell's functions, but it is the Nucleus that acts as the 'control center.'
