the results indicate that , without viomycin , the noncognate peptidyl-trna is weakly held in the ribosomal a site and support the proposal that the release of peptidyl-trna occurring during protein synthesis in vivo is related to a ribosomal editing mechanism which discards mistranslated nascent proteins [ menninger , j. r. ( 1977 ) mech . ageing dev . 6 , 131 ] .
