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.
The ribosomes converts mRna with tRna into amino acids and thus,  proteins. The ribosomes are made of two subunits (which are in turn  made of rRNA and proteins); these tiny structures clamp onto mRNA  coming out of the nucleus and translate it into a strand of amino  acids.
