What are the minimum parts required for a functional virus? answers?

The four minimum parts required for a functional virus are: Virus genome, accessory proteins (if a virus needs an enzyme immediately in a new cell) and capsid/structural proteins. In case of enveloped virus, which is a virus that orders the cell to create parts of the membrane to send replications off in their own capsules also e nvelope proteins are required in order to virus to function.

A virus requires three of four parts at a minimum to function, depending on the type of virus: the virus genome, accessory proteins, and the capsid (or structural proteins) are required for all viruses. If the virus is enveloped, it will also require envelope proteins. Envelope viruses use the cell in a different way that regular viruses, the latter of which replicates until the cell explodes; instead, they order the cell to create parts of the membrane to send replications off in their own capsules, thus not destroying the cell as the others do.
