What are good analogies for nucleus

The best analogy for the nucleolus in eukaryotic cells is a factory that makes tools that are used to build other resources. The primary function of the nucleolus is to combine and construct ribosomes. The primary function of ribosomes is to build proteins necessary for the cell

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
