As mentioned above, ribosomes are the molecular machines responsible for protein synthesis. A ribosome is made out of RNA and proteins, and each ribosome consists of two separate RNA-protein complexes, known as the small and large subunits.
Structure. The ribosome is made up of two parts, called subunits. The larger of the two subunits is where the amino acids get added to the growing protein chain. The small subunit is where the mRNA binds and is decoded.Each of the subunits is made up of both protein and ribonucleic acid (RNA) components.The small ribosomal subunit is made up of one ribosomal RNA (rRNA) and approximately twenty-one proteins in prokaryotes (bacteria) and approximately thirty-three proteins in eukaryotes (mammals).t binds to a messenger ribonucleic acid (mRNA) and reads the information contained in the nucleotide sequence of the mRNA. Transfer RNAs (tRNAs) containing amino acids enter the ribosome in a special pocket, or binding site, called the acceptor site (A site).
