: To prevent errors, it employs a "proofreading" complex (nsp10–nsp14). Research found that this complex is highly specific—it looks for the presence of certain chemical groups (2′OH and 3′OH) on the RNA backbone to identify where it needs to work.
: Scientists discovered that certain analogues, like Cordycepin, can "trick" the virus. The RdRp incorporates these fake building blocks, causing the "photocopier" to jam and the "proofreader" to fail because it doesn't recognize the modified chemical structure. Therapeutic Potential
