In eukaryotic cells, ribosomes have 2 subunits that are formed in the nucleus and then exit the nucleus to form the ribosome. These subunits are formed of 4 rRNA strands of which 3(5.8S,5S,28S) are produced in the nucleolus of the nucleus and 1(5S) is produced outside the nucleolus in the nucleus. The 2 subunits are formed before they exit the nucleus creating a small subunit(18s and 33proteins) and the large subunit (5S,5.8S,28S and 49proteins). These subunits exit the nucleus and when an mRNA is to be translated it attaches itself to the small subunit and the large subunit then locks into the small subunit like a cup and the process begins.
The Ribosomes are formed in Nucleolus.
(i hope that's your answer)
The process is involved and incompletely known, but the raw materials are ribosomal RNA and proteins found in the nucleolus of cells. They are assembled in the nucleolus.
Ribosomes are formed in the nucleolus of the cell

Ribosomes consist of two subunits, which contains a type of RNA known as ribosomal ribonucleic acid (rRNA).

Ribosomal Subunits

Yes, rDNA does form ribosomal subunits. This occurs inside the nuclear membrane at an area called the nucleolus. Two subunits are formed consisting of a small (40S) and a large (60S) subunit. These subunits are then leave the nucleus and assemble in the cytoplasm or on the Rough Endoplasmic Reticulum.
What is the fate of the newly formed subunits? What is the fate of the newly formed subunits?

Nuclear Pores
In the nucleolus of the nucleus to be exact. Google nucleolus.
Ribosomes are composed of RNA and proteins.
ribosomal RNA
Ribosomes consist of two subunits, which contains a type of RNA known as ribosomal ribonucleic acid (rRNA).
This mass is called the nucleolus. It is involved in RNA production as well as the formation of ribosomal subunits.
