Introduction:-

Ribosomes are complex molecular machine found inside the living cells that produces protein from amino acid during a process called protein synthesis.Ribosomes are specialised cells organelles and are found in both prokaryotic cells and eukaryotic cells.Every cell living cell require ribosomes for protein factory. The cell organelles are function by binding to a mRNA.
Ribosomes are granular structures first observed under electron microscope as dense particles.
