            In this
            diagram, RNA synthesis has already been proceeding
            for some time: the dsDNA at the left was opened,
            transcribed, and then re-closed.The RNAPol molecule
            opens the dsDNA,  the RNA molecule is
            synthesized in the 5' 3' direction, off of
            the template DNA strand. The
            5' end is transcribed first, and afterwards is
            unchanged
