Step 1
B. neuraminidase.
Answer
The enzyme necessary for ongoing virus replication in the influenza virus is neuraminidase. This enzyme plays a crucial role in the viral life cycle by cleaving sialic acid residues from the host cell surface, facilitating the release of newly formed virions from the host cell. Neuraminidase is essential for viral spread within the respiratory tract, making it a key target for antiviral drugs.
