Viral polymerase mechanism is a fundamental concept and active research area in molecular virology that investigates the detailed biochemical and structural processes governing the synthesis of viral nucleic acids by viral polymerases. This field seeks to understand the molecular steps of viral genome replication and transcription, including enzyme-substrate interactions, catalysis, processivity, and fidelity, providing essential knowledge for understanding viral life cycles, pathogenesis, and identifying targets for antiviral therapies.
