Researchers determined that the lipids found in the virus form a bilayer membrane surrounding the virus and are obtained from the membrane of a host cell during the virus maturation an exit from the whole cell further research revealed that this virus specifically infects the species of fish in the tropical areas interestingly the virus is also capable of infecting a very similar species of fish that is found in the arctic ocean is a sample of the virus located from the arctic species of fish what is the most likely truth about the percentage of unsaturated lipids in the virus sample compared to a sample isolated from a tropical counterpart
