Phages genes

Cro, by contrast, acts purely as a repressor. When it is bound to its high-affinity site at OR3, it prevents repressor synthesis by obstructing the access of polymerase to the left-hand promoter. In the absence of repressor, RNA polymerase can bind to the Cro promoter, and Cro can be synthesized along with the early phage genes to its right.
