<prompt> Not true about viral envelop-Lipid is derived from host cellsProtein is derived from virus itselfDissolves in solventPropagates in next generation  <response>: Ans. is d i.e., Propagates in next generation o Envelope is lipoprotein in nature, lipid is derived from host cell, while protein is virus coded,o Enveloped viruses are susceptible to the action of lipid solvents like ether chloroform and bile salts.o Envelop is not propagated in next generation. Rather progeny virions synthesize new envelop by self protein and host lipid. Sequence of events is as follows :-Attachement of parent enveloped virus into host cellUncoating removal of envelop with injection of viralnucleic acid into host cellMultiplication of nucleic acid and synthesis of structural proteinMaturation of daughter virionEnvelope lipid derived from host cell membrane duringthe process of buddingIncorporation of virus coded protein in lipid envelop derivedfrom host cells to make lipoprotein envelopRelease of progeng virions
