the correlation between the level of messenger ribonucleic acid ( mrna ) specific for the argecbh gene cluster ( argecbh mrna ) measured by ribonucleic acid-deoxyribonucleic acid ( rna-dna ) hybridization and the rates of synthesis of n-acetylornithine deacetylase ( arge enzyme ) and of argininosuccinate lyase ( argh enzyme ) of escherichia coli strain k-12 were determined for steady-state growth with and without added l-arginine and during the transition periods between these two states .
