Barnase Growth Control

This contruct works by expressing background levels of Barstar with Barnase inducible such that it will overwhelm Barstar when induced.Higher levels of Barnase expression resulted in lower rates of growth in the bacteria, affirming the principle of Barnase-based growth control for the genetic fence, and confirming the results from Berkeley 2008.
