The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells. In 1955, George E. Palade discovered ribosomes and described them as small particles in the cytoplasm that preferentially associated with the endoplasmic reticulum membrane.

Who first discovered rRNA?

The discovery of RNA began with the discovery of nucleic acids by Friedrich Miescher in 1868 who called the material 'nuclein' since it was found in the nucleus.

Where is ribosomal RNA found?

Molecules of rRNA are synthesized in a specialized region of the cell nucleus called the nucleolus, which appears as a dense area within the nucleus and contains the genes that encode rRNA.
