Detailed explanation-1: -A virus that has an outer wrapping or envelope. This envelope comes from the infected cell, or host, in a process called “budding off.” During the budding process, newly formed virus particles become “enveloped” or wrapped in an outer coat that is made from a small piece of the cell’s plasma membrane.

Detailed explanation-2: -Which of the following are true about viral envelopes? They are composed of host membrane., They can contain host-encoded proteins., They can contain virus-encoded proteins., and They are important for binding to host cells.

Detailed explanation-3: -Newly released virions can infect adjacent cells. A lysogenic cycle kills the host cell is not true statement of Viral replication.

Detailed explanation-4: -Viral envelopes consist of a lipid bilayer that closely surrounds a shell of virus-encoded membrane-associated proteins. The exterior of the bilayer is studded with virus-coded, glycosylated (trans-) membrane proteins.
