Ribosomes are the particles present in the cells in large numbers and mainly serve as a site for protein synthesis. They are present as free particles in both prokaryotic and eukaryotic cells and also attached to the membrane of the endoplasmic reticulum in the case of eukaryotic cells. The Discovery of ribosomes was in the year 1955 by a Romanian-American cell biologist George E. Palade, during his discovery he found that ribosomes are associated with the endoplasmic reticulum in eukaryotic cells.
Along with protein synthesis, they also function by binding to a messenger ribonucleic acid (mRNA) and decoding the information carried by the nucleotide sequence of the mRNA. The transfer RNA’s having amino acids, enters into the ribosomes at the acceptor site. Once after getting added up, it further adds amino acid to the growing protein chain on tRNA.
