Operоn Mutаnts. Scientists hаve isоlаted a variety оf different mutations which affect E. coli’s ability to effectively metabolize lactose. Record the effect of each of the following mutations in order to complete the table. # Description Result 1 lacI gene mutated so that lacI protein is not produced. (e.g. a Mutation in the lacI promoter) [blank1] 2 lacP promoter is mutated so that RNA polymerase cannot bind. [blank2] 3 Lactose permease is not produced due to a mutated ATG start codon in the lacY gene. [blank3] 4 lacI gene mutated such that the repressor is produced but that it cannot bind to the operator. (e.g. a mutation in the DNA binding region) [blank4] 5 A mutation in the lacI promoter which vastly increases the amount of repressor that is present. [blank5] 6 lac operator is mutated so that it can no longer bind to the repressor. [blank6]
