Select all of the following that are true about the viral envelope. present in HIV contains embedded proteins composed of lipids derived from host cell membrane The capsid is a coating that surrounds the DNA or RNA of a virus. WebThe enveloped viruses may, therefore, assume different shapes (pleomorphic). Depending on the virus, the carbohydrate-protein complexes (glycoproteins) may form projections on the outer surface of the envelope. These projections are called spikes or peplomers. The spikes have definite size and they are distributed evenly at definite intervals.
