Final answer:
Ribosomal subunits in eukaryotic cells are assembled in the nucleolus and then transported to the cytoplasm, where they function in translation.
Step-by-step explanation:
Eukaryotic cells have ribosomes that consist of a small 40S subunit and a large 60S subunit.
These subunits are assembled in the nucleolus and then transported to the cytoplasm, where they function in translation.
The small subunit binds the mRNA template, while the large subunit binds tRNAs.
