Draw a Simple Map of the Lactose Operon Indicating the Relative

Essay

Draw a simple map of the lactose operon indicating the relative positions of promoter, operator, CRP-binding site, repressor gene (I), and the structural genes of the operon (A, Y, Z). Indicate where the CRP protein binds within this operon. When it is bound to this site, does the CRP protein have a positive or negative effect on gene expression in this system?
