Here's a specific problem related to DNA-protein interactions and regulation for a chemistry student to solve:How does the binding affinity of a transcription factor to DNA affect gene expression? Investigate the factors that influence this interaction using experimental data and molecular modeling techniques. Specifically, determine how changes in concentration, temperature, pH, and DNA sequence impact the stability and specificity of the protein-DNA complex. Based on your findings, propose potential strategies for regulating gene expression through targeted modulation of transcription factor-DNA interactions.
