First discovered in E. coli, these objects include a promoter site and regions of DNA that bind repressors or activators.
The formation of hairpin-like structures can repress these objects in a process called attenuation. When bound to cAMP, the catabolite activator protein binds upstream of one of these objects to recruit RNA polymerase. Their activity is regulated by IPTG and can be monitored by the breakdown of X-gal. One of these objects produces permease, transacetylase, and (*) beta- galactosidase enzymes. First discovered in E. coli, these objects include a promoter site and regions of DNA that bind repressors or activators. For 10 points, identify these objects that regulate gene expression, famous examples of which include the "trp" and "lac" ones.
