Invagination or injection of genome into cell describes what step of the viral life cycle?

Select the correct answer(s).

(0/0)

Explanation

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?

Select the correct answer(s).

(0/0)

Explanation

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

SSPE is an example of what disease pattern?

Select the correct answer(s).

(0/0)

Explanation

SSPE is subacute sclerosing panencephalitis which is a measle complication that arrises 2-6 years after measles infection and is fatal

Select the definition of persistent and chronic disease pattern

Select the correct answer(s).

(0/0)

Explanation

Short-lived self limiting infection = acute, Asymptomatic = subclinical, Dormant virus = latent, Virus replicates at normal rate but disease takes years to manifeset = slowly progressive
