Paragraph starter
The methodology employed in this design project was informed by research such as Joung et al. (2015), which demonstrated that template-based modeling protocols, when combined with energy-based refinement techniques like molecular dynamics simulations, can significantly improve the accuracy and realism of 3D structural predictions. This approach was adopted to leverage existing computational data and enhance the fidelity of our own modeling efforts.
