Question

multiple choice question
which organelle functions as the control center of a eukaryotic cell?

rna
dna
nucleus
nucleoid

Explanation:

To solve this, we analyze each option:

• RNA: A nucleic acid, not an organelle.
• DNA: A nucleic acid, not an organelle.
• Nucleus: In eukaryotic cells, the nucleus contains DNA (genetic material) and controls cell activities (like growth, metabolism, reproduction) by regulating gene expression. It is an organelle.
• Nucleoid: Found in prokaryotic cells (not eukaryotic), it's the region with DNA but not a membrane - bound organelle like the nucleus in eukaryotes.

Answer:

C. Nucleus
