Aleksandr Afanasev extended the epam/ketcher macromolecule editor to support DNA antisense chain creation alongside existing RNA functionality, enhancing the tool’s ability to model nucleic acid structures. He updated the core editor logic and comprehensive test suites to ensure accurate representation and manipulation of both RNA and DNA antisense chains within the editor. Working primarily with JavaScript and TypeScript, Aleksandr applied front end development and testing skills to broaden the editor’s capabilities for cytoscience workflows. This focused contribution addressed the need for seamless DNA antisense modeling, delivering a targeted feature with depth in both implementation and validation over the project month.

February 2025: Delivered DNA antisense chain creation in the epam/ketcher repo, extending the macromolecule editor to support both RNA and DNA antisense chains. This work updated tests and core editor logic to accurately represent and manipulate nucleic acid structures, enabling seamless modeling of DNA antisense alongside RNA within the editor. The contribution enhances modeling fidelity and broadens cytoscience workflows for nucleic acid design.
