Not true about viral envelop?
Ans. is 'd' i.e., Propagates in next generation Envelope is lipoprotein in nature, lipid is derived from host cell, while protein is virus coded. Enveloped viruses are susceptible to the action of lipid solvents like ether, chloroform and bile salts. Envelop is not propagated in next generation. Rather progeny virions synthesize new envelop (by self protein and host lipid).
Lipid is derived from host cells
Protein is derived from virus itself
Dissolves in solvent
Propagates in next generation
