Protein Synthesis, Processing, and Regulation
... A noteworthy feature of ribosomes is that they can be formed in vitro by self-assembly of their RNA and protein constituents. As first described in 1968 by Masayasu Nomura, purified ribosomal proteins and rRNAs can be mixed together and, under appropriate conditions, will reform a functional riboso ...
