The nucleolus is the small dense region in the nucleus where the assembly of ribosomes begin. It makes up 25 percent volume of the cell nucleus and its malfunction may cause diseases in the human body.
The region of the nucleus in which ribosome subunits are put together is the nucleolus.
The nucleolus is a distinct region within a nucleus, into which parts of some of the chromosomes project. These chromosomal segments include many copies of genes that code for ribosomal RNA (rRNA). In humans, for example, three of the four types of rRNA are synthesized within the nucleolus.
A functional ribosome has two subunits, which come together in the cytoplasm when a molecule of messenger RNA is being translated. The subunits are assembled partly within the nucleolus and partly within the cytoplasm.
For assembly in the nucleolus, proteins must be transported from the cytoplasm, where they are synthesized, into the nucleolus; they enter the nucleus via nuclear pore complexes. There are approximately 80 proteins altogether in the two subunits.
The part of the cell that assembles ribosomes is the nucleolus. The nucleolus is located inside of the nucleus.
The small dense region in the nucleus where the assembly of ribosomes begin is called the nucleolus. It becomes enlarged during protein synthesis.

The assembly of ribosomes begins in a small dense structure called the nucleolus. The nucleolus is a non-membrane bound structure composed of proteins and nucleic acids found within the nucleus.
A prokaryote aka a bacterium doesn't contain a nucleus but it does contain small ribosomes.
Ribosomes are made in the nucleolus, which is a small organelle located inside the nucleus.

The rough endoplasmic reticulum is studded with small granular structures called ribosomes. Ribosomes synthesize proteins.

The small unit found in ribosomes are called subunits. They are denoted according to their sedimentation coefficients in the Svedberg units. The 40S is the subunit for eukaryotic ribosomes, while the 30S is the subunit for prokaryotic ribosomes.

Ribosomes are made inside the nucleolus, which is inside the nucleus of the cell. Ribosomes function to synthesize proteins. ***************************** it controls which qenes qet used.
The codons are transcribed onto messenger RNA (mRNA) which is small enough to fit through the pores of the nucleus. This then attaches to the ribosomes where the codons are translated.
