Determine the nature of the expression of the lacZYA genes, represented by L, and label each genotype as constitutive, inducible, or no transcription in the presence of lactose. Assume that all promoters are wild type. Symbol Representation I− lacI mutant cannot bind to the operator IS lacI mutant always binds to the operator OC Operator mutant that prevents repressor binding F' the wild‑type operator, O+, and lacI gene on a plasmid L lacZYA genes
