Detailed explanation-1: -The ribosome consists of two subunits, each of which is made up of ribosomal RNA (rRNA) and many ribosomal proteins . Structurally, ribosomes of prokaryotes and eukaryotes vary by the types of rRNA and protein molecules found in them. The prokaryotic 70S ribosome has a small 30S and a large 50S subunit.

Detailed explanation-2: -Ribosomal RNA organizes into two types of major ribosomal subunit: the large subunit (LSU) and the small subunit (SSU). One of each type come together to form a functioning ribosome. The subunits are at times referred to by their size-sedimentation measurements (a number with an “S” suffix).

Detailed explanation-3: -Ribosomal proteins enter the nucleolus and combine with the four rRNA strands to create the two ribosomal subunits (one small and one large) that will make up the completed ribosome (see Figure 1).

Detailed explanation-4: -Ribosomal RNA (rRNA) In the large ribosomal subunit there is one small RNA molecule called the 5S RNA, which is usually composed of 120 nucleotides. The large RNA molecule in this subunit is called the 23S RNA in eubacteria. Its size also varies and sometimes it is present as several pieces.

Detailed explanation-5: -Answer and Explanation: The name of the organelle that manufactures the components of ribosomes is the nucleolus. The nucleolus is a part inside of the nucleus. It creates the protein and ribosomal RNA subunits of the ribosome.
