What is a Cell Made Up of. What is the Structural Organisation of a Cell

Ribosomes are small granular structures made up of ribonucleic acids (RNA) and proteins. They occur free in the cytoplasm as well as attached to the outer surface of the rough endoplasmic reticulum. Each ribosome consists of two subunits – a small subunit and a large subunit. At the time of protein synthesis, many ribosomes get attached to messenger RNA and form a structure called polyribosome or polysome.

Functions of Ribosomes: Ribosomes play an important role in protein synthesis. So they are called, ‘protein factories’ of the cell.
