  • b)
    Mutant 2 has mutation in operator
  • c)
    Mutant 2 has mutation in promoter.
  • d)

Verified Answer
Given below are the different strain of E.coli mutants isolated.Which ...
Mutation in either the repressor gene (lac I) or operator sequence  may fail to regulate the expression of the structural genes, resulting in constitutive expression of beta galactosidase and permease enzyme (mutant 1). Mutation in the promoter sequence would not allow the RNA polymerase to bind the promoter sequence, thereby inhibiting the expression of beta galactosidase and permease enzymes (mutant 2). Mutation in the structural gene, Z will result in no beta galactosidase synthesis, but will not impact the synthesis of permease enzyme(mutant 3).
