The Nucleus and its Functional Domains

ID #1820

Is it right to say that "ribosome assembly" means each subunit is assembled with processed rRNA and other proteins, and not the assembly of large subunit and small subunit together? So the large and small subunits come out of the nucleus separately?


Yes, your interpretation is correct. Assembly of subunits in the nucleolus means combining the rRNA and the ribosomal proteins in a given subunit, NOT bringing together large and small subunits. That doesn't happen until they are out in the cytoplasm.
