WebJun 8, 2024 · Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes. Mitochondria are responsible for ATP production; the endoplasmic reticulum modifies proteins and synthesizes lipids; and ... WebA. Ribosomes contain DNA and protein B. Ribosomes are active in carbohydrate synthesis C. Ribosomal subunits leave the nucleus after being formed by the nucleolus D. Polyribosomes are the subunits of ribosomes E. Ribosomes are only found associated with the endoplasmic reticulum in prokaryotic cells.
