Helicase facts
WebThe answer will be Helicase. Explanation: The helicase enzyme unwinds the DNA leading to the formation of "Replication fork" which is literally two separated single strands of DNA. It acts on hydrogen bonds present between those nucleotides ( base pairs ), hence unzipping or unwinding the double helix structure. Web16 feb. 2024 · ABSTRACT. Introduction: Coronaviruses encode a helicase that is essential for viral replication and represents an excellent antiviral target.However, only a few coronavirus helicase inhibitors have been patented. These patents include drug-like compound SSYA10-001, aryl diketo acids (ADK), and dihydroxychromones.
