Webb9 apr. 2004 · Viral particles mediate the transfer of the viral genome and accessory proteins from an infected host cell to a noninfected host cell. The task involves packaging the viral genome (RNA or DNA) and accessory proteins, releasing the package from the infected cell, protecting the essential components during extracellular transmission, and … WebbWhich statement(s) is true? a) Infectious protein particles called prions are implicated in Creutzfeldt-Jakob disease b) Viruses can infect plant and animals cells c) RNA viruses are called retroviruses d) Antibiotics do not work against viruses e) All are true Which statement is false?
Webb12 apr. 2024 · These are called “surface receptors” – and work a little like a lock and key: a virus can only invade a cell is its surface molecule (the key), matches the receptor (the lock) on the host cell. The SARS-CoV-2 key is the spike protein which matches the ACE2 receptor lock on target cells.
WebbRabies virus, scientific name Rabies lyssavirus, is a neurotropic virus that causes rabies in humans and animals.
