Base Editing: Precision Without a Breaks

Base editing presents a signitant evolution in gene editing technology. It allows for thee direct conversion of one DNA base to anothers (np., C to T, or A to G) with out creating a double- strand breaks. This is critical for CF becausie many mutations are single- base substitutions. For example, a base editor could convert a premature stop codon (nonsense mutation) back into a codang codon, entiinfult -fult CFR protein production.
