Domains of Life; Prokaryotic vs. Eukaryotic Cells

ID #2112

I have a question about ribosomal subunits. Are subunits both produced and assembled in the nucleus?

During our quick tour of eukaryotic cells during lecture, I described things that are occurring in the nucleus. One of them, as described, was "production and assembly of the protein synthesizing machinery." This was my way of talking about ribosomes before we had really introduced ribosomes. The ribosomal subunits are indeed produced and assembled in the nucleus (specifically in the nucleolar region), although a large subunit doesn't come together with a small subunit to synthesize a protein until they are in the cytoplasm.
