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.
Ribosomes are made up of two subunits, cleverly referred to as the small subunit and the large subunit. You may also hear them called the 30S and 50S in bacteria or the 40S and 60S in eukaryotes. The small and large subunits join together to make 70S or 80S, respectively. Ribosomes really have two tasks: decode messenger RNA (mRNA) and synthesize proteins. The decoding function is performed by the small subunit and the protein synthesis part is performed by the large subunit. Talking to my scientist friends, I would call the ribosome a ribonucleoprotein complex, or RNP.
