Abstract:

The observations made in this report indicate that gene z contained at least two distinctive segments which determined the structure of different peptides whose association constituted the protomere of beta-galactosidase. Complementation studies in vivo have shown, among other things, that deletions with a feeble extension M15 and 05 are weakly complementable with point mutants located between the markers G and 242. These observations suggested that the segment located between the operator and peptide omega itself determined the structure of at least two distinctive peptides.
