When the RNA polymerase reaches the termination site, rho first freezes the structure of the polymerase and then invades the exit channel to destabilize the enzyme, causing it to release the RNA.

Like the Lambda repressor, the cII protein is a transcriptional activator. It binds to a site upstream of a promoter called PRE (for repressor establishment) and stimulates transcription of the cI (repressor) gene from that promoter.

Philadelphia chromosome

Reciprocal translocation between the long arm of chromosome 22 and the tip of the long arm of chromosome 9. This translocation produces a shortened chromosome 22, called the Philadelphia chromosome.
