AFAIR from my biochem lessons, all bacteria have circular DNA, and the 
transcription proteins use a specific sequence of base pairs to define 
start and end points.

And start and end points are not required, as all you need is a promoter 
sequence for the RNA polymerase to bind to, and a termination sequence to 
tell the RNA polymerase to stop.

Oh, and for Karl Pelzer, Adenine always binds to Thymine (in DNA) or 
Uracil (In RNA), and Cytosine always binds to Guanine.

Bye for now,
