The C-terminal region of the herpes virus structural protein VP16 transcriptional activation domain was fused to the DNA-binding domain of LexA protein to create a VP16-LexA chimaera

The new gene encoding the VP16-LexA fusion protein was inserted into a plasmid and transferred to yeast, along with a plasmid that contained theGAL1 gene promoter fused to the bacterial ?-galactosidasegene, lacZ. This is experiment A. The new gene encoding the VP16-LexA fusion protein was inserted into a plasmid and transferred to yeast, along with a plasmid that contained theGAL1 gene promoter containing a LexA binding site fused to the bacterial ?-galactosidasegene, lacZ. This is experiment B. Which of the following graphs correctly show the expected levels of GAL1-lacZ fusion gene expression?
