For each E coli genotype and condition in the followingtable, choose which sets of functional proteins will or will not beproduced.

All grown in media with no/low glucose.

I^S indicates a super-repressor (it can’tbind to lactose/inducers).

O^C indicates a constitutive operon (norepressor can bind to this region of DNA).

I^- ; Z^- ; Y^-eachindicate an allele that does not produce a functional protein.

P^- indicates a mutation in the promoterregion such that RNA polymerase does not bind.
