Yоur reseаrch grоup mаkes а deletiоn mutation in the operator of the lac operon that causes LacI to no longer bind there under any circumstance. Indicate whether each expected outcome is logical (true or false). In conditions where glucose is abundant, the addition of allolactose to a culture of this mutated bacteria will trigger an immediate significant increase in lac operon expression. [blank1] In conditions where glucose is low, the addition of allolactose to a culture of this mutated bacteria will trigger an immediate significant increase in lac operon expression. [blank2] Adding a synthetic chromosome with a full, normal lac operon will restore the bacteria to wild type (100% normal) lac operon regulation and function (i.e. the operator deletion mutation you introduced is "recessive"). [blank3] Adding a synthetic chromosome with a normal lacI gene will restore the bacteria to normal lac operon function (i.e. it will rescue the mutation). [blank4]
