Prime editing: Search and replace for human DNA | GeneInCell | 2026

Prime editing is a next-generation gene editing tool designed to precisely rewrite DNA—like a search-and-replace function for the human genome. In this episode, we break down how prime editing works, the chemistry behind it, and why it offers a powerful alternative to traditional CRISPR by making targeted changes without creating double-strand breaks. We also explore its applications in disease correction, its growing path toward the clinic, and the key challenges that still stand in the way.
