Prime editing is an advanced genome editing technology that enables precise genetic modifications without inducing double-strand breaks or requiring donor DNA templates. Prime editing has rapidly become a versatile tool, supporting a wide range of genetic modifications, including point mutations, insertions and deletions. Here we examine the evolution of prime editing technologies, detailing advancements from the initial prime editing systems to recent innovations that enhance editing efficiency. Through structural modifications and improved delivery methods, prime editing has expanded its applicability across eukaryotic systems. By enabling access to previously challenging mutations, prime editing opens new avenues for therapeutic development and precision genetic research, with efficiency, specificity and accessibility expected to shape its future impact in genome engineering.
