Nucleus function?

Nucleus function?

• A. Site of protein synthesis
• B. Digestive enzymes
• C. Powerhouse of the cell
• D. Contains DNA and controls cell activities

Answer: (D)

The nucleus acts as the cell’s control center. It houses the DNA, which contains all the instructions for making and regulating the proteins a cell needs. By transcribing DNA into messenger RNA, the nucleus determines which proteins get made and when, helping regulate activities and responses in the cell. The other options point to specific roles of other organelles: protein synthesis happens on ribosomes, digestion occurs in lysosomes, and energy production happens in mitochondria. So containing DNA and directing cell activities through gene expression best captures the nucleus’s function.
