Abstract:- Transciption is one <strong>of</strong> the important steps in the central dogma <strong>of</strong> molecular biology. Using<br />
RNA Polymerase <strong>of</strong> Escherichia coli and T7A1 promoter from T7 phage as the model system, we<br />
probe the sequence dependence <strong>of</strong> the unzipping force <strong>of</strong> transcription at the single molecule level. We<br />
unzip wild type and various mutated sequences <strong>of</strong> DNA with RNA-polymerase attached to each <strong>of</strong><br />
them and determine the change in the binding force at the beginning <strong>of</strong> the unzipping <strong>of</strong> the<br />
transcription bubble. We thus determine the role <strong>of</strong> each individual base pair <strong>of</strong> the consensus<br />
promoter sequence affecting the binding <strong>of</strong> RNA-Polymerase to the promoter.<br />
