Transcriptional and post-transcriptional control of beta-galactosidase synthesis
Abstract
lac messenger ribonucleic acid synthesis is dissociated from its translation in certain lac operon mutants. More beta-galactosidase messenger ribonucleic acid (as determined by hybridization) is made in fully induced lacOc mutants and in trp-lac fusions than is eventually translated into enzyme. Consequently, beta-galactosidase synthesis may be post-transcriptionally controlled under these conditions.
