updna

Updna, short for updateable DNA, is a conceptual framework in synthetic biology and data storage that envisions mechanisms for modifying information already encoded in DNA without rewriting entire sequences.

In proposed models, updna relies on programmable editing tools such as base editors, prime editors, or site-specific

Potential applications include storing digital data in DNA with the ability to patch or upgrade data post-assembly

Challenges include maintaining fidelity, avoiding off-target edits, ensuring compatibility with existing storage formats, ethical and biosafety

Origin and status: The term is used mainly in speculative discussions and some fiction; not widely adopted

Related topics include DNA data storage, base editing, recombinase systems, and synthetic biology.
