Draw a diagram of the active site

You identify a novel bacterial species from a deep sea hyrothermal vent that lacks 5′-dNTPs. The DNA in this organism has the normal anti-parallel double stranded helix with 3′- 5′ phosphodiester bonds. You discover that the DNA polymerase in this bacterium synthesizes DNA in the 3′-5′ direction. It requires a primer, a template, Mg2+ and activated precursors. Draw a diagram of the active site of this enzyme showing all of the important elements.
