Question

1. For the genotypes and conditions (lactose present or absent) shown in the following table predict whether functional enzymes, nonfunctional enzymes, or no enzymes are made. 

 

2. Even though the LacZ,Y and A structural genes are transcribed as a single polycistronic mRNA, each gene contains the initiation and termination signals essential for translation. Predict what will happen when a cell growing in the presence of lactose contains a deletion of one nucleotide early in the Z gene and early in the A gene.
