Parts A-C show the genotypes for partial diploid strains of the lac operon. Gene names have been simplified (ie, LacZ is shown as Z), with alleles shown as standard notations. There are two copies of the operon, one line is the copy in the genome and the other line is on a plasmid. In the blanks, indicate the following based on regulation of the structural gene in the header, choose "functional' if you expect that any amount of normal enzyme will be made, "nonfunctional" if you expect that transcription occurs but the enzyme is mutated, or "no transcription if the structural gene is not transcribed. Assume glucose is absent. LacY Enzyme Activity Genotype of Strain Absence of allolactose I-P+O+Z+Y+ I+P+ O° Z-Y- 1+ P+ OF Z+Y- PP+O+Z-Y+ 1-P+O+Z+Y- I+P-O+Z-Y+ Presence of allolactose
