Scientists finally see DNA “zip” itself together for the first time

Дата публикации: 10-09-2026 03:17:17

Scientists have directly observed how two negatively charged DNA molecules can pair up despite normally repelling each other. Positively charged metal ions appear to bridge the gap, helping matching DNA helices align groove for groove like a molecular zipper. The discovery confirms a theory proposed two decades ago and could help researchers understand DNA interactions involved in cancer and other cellular processes.
