Question

The promoters of positively controlled operons require activator proteins because The promoters of positively controlled operons require activator proteins because they are needed to bind to the allosteric site of RNA polymerase. RNA polymerase easily recognizes the consensus sequence. the promoters bind RNA polymerase weakly and utilize activator proteins to help RNA polymerase recognize the promoter. they are required to inactivate the repressor proteins.

Answer 1

the promoters bind RNA polymerase weakly and utilize activator proteins to help RNA polymerase recognize the promoter.

Step-by-step explanation:

The promoters of positively controlled operons require activator proteins because the promoters bind RNA polymerase weakly and utilize activator proteins to help RNA polymerase recognize the promoter.
