The small spherical objects in the nucleus of a cell?

The small spheres in the nucleus of the cell are the ribosomes. They are responsible for protein synthesis. They take mRNA and match it with the corresponding amino acid though tRNA. The ribosomes synthesize long chains of amino acids, and these large chains are used to form different proteins.
It is important to note that ribosomes are only created in the nucleus. They are then placed in the rough endoplasmic reticulum or in the surrounding cytoplasm.
