in what locations the mutation which prevent the binding of a certain protein to lts regulatory sequence occur?(lac l→CAP site→Promotor→Operator→lac Z→lac Y→lac A)
operator locus
(a certain protein=repressor protein(product of the lac l gene))
this mutation results in increased transcription of the genes of the lac operon in lactose-deficient media, although the presence of glucose will prevent maximal transcriptional activity geneticsbiologyUWorld May 1, 2020, 12:56 AM HirotoShishido
