WebbThe ribosome autocatalytic cycle. To synthesize ribosomes de novo, existing ribosomes must create more than 50 different ribosomal protein subunits. The mRNAs for the ribosomal proteins are transcribed by RNA polymerases. A subgroup of the ribosomal proteins directly bind to rRNA, which is also transcribed by RNA polymerases. WebbRibosome display selects required molecules by linking individual proteins (phenotype) with their corresponding mRNAs (genotype) through the formation of stable Protein-Ribosome-mRNA (PRM) complexes. By affinity interaction with an immobilized ligand, the captured PRM complexes are recovered as cDNA using RT-PCR from the ribosome …
