(0/0)

Penjelasan

Attachment = surface spikes attach to cell membrane, Replication = making of more DNA/RNA proteins, Assembly = Capsid surrounds RNA, Release = Budding trough membrane acquiring an envelope

What is not a mechanism of anti-virals?

Pilih Jawapan yang Betul

(0/0)

Penjelasan

Viral and cellulara receptors are an example of anti-virals targetting attachment, Anti-virals targetting entry actually BLOCK the fusion of envelope and cell membrane, Anti-virals targetting enzymes are targetting the replication stage of the life cycle. In terms of release stage, Tamiflu inhibits neurominidase which cleaves the bond of influenza budding out of the cell
