Verified step by step guidance

Understand that the nucleus is a key organelle in eukaryotic cells, responsible for housing the cell's genetic material.

Recognize that the nucleus is membrane-bound, meaning it is enclosed by a nuclear envelope, which separates its contents from the cytoplasm.

Identify the primary function of the nucleus: it contains DNA, which is organized into chromosomes, and is crucial for regulating gene expression and cellular activities.

Note that the nucleus is not involved in generating ATP or directly synthesizing proteins; these functions are carried out by other organelles like mitochondria and ribosomes, respectively.

Conclude that the correct description of the nucleus is that it is a membrane-bound organelle containing the cell's genetic material and controlling cellular activities.
