Question

How are ribosomes made in the nucleolus?

Answer 1

Ribosome

1. Ribosome is a cell organelle found freely in the cytoplasm or attached to the rough endoplasmic reticulum.
2. It is a cell organelle found in both prokaryotic and eukaryotic cells.
3. It is a membrane-less organelle involved in protein synthesis.
4. They are made up of ribosomal RNA and proteins.
5. Prokaryotic cells lack a nucleus, so ribosomes are formed in the cytoplasm only.
6. In eukaryotic cells, ribosomes are formed in the nucleolus present in the nucleus.
7. In the nucleolus, these ribosomal proteins and rRNA assemble and produce ribosomal subunits.
8. These subunits are exported from the nucleus and form the ribosomes in the cytoplasm.
