Which cellular component acts as the brain of the cell and houses genetic material?

• A. Cytoplasm
• B. Cell Membrane
• C. Organ
• D. Nucleus

Answer: (D)

The nucleus serves as the control center of a cell, housing the genetic material in DNA. It organizes DNA into chromosomes and regulates gene expression, directing which proteins are produced and when. This regulatory role is why it’s considered the “brain” of the cell, coordinating overall cellular activities. The cytoplasm is where many metabolic reactions occur, the cell membrane controls substance movement, and an organ is a general term not specific to a single cellular component. So the nucleus is the component that both houses genetic material and directs cell function.
