question 47

Multiple Choice

What is the main structural difference between enveloped and nonenveloped viruses?

• A)Enveloped viruses have their genetic material enclosed by a layer made only of protein.
• B)Nonenveloped viruses have only a phospholipid membrane, while enveloped viruses have two membranes, the other one being a protein capsid.
• C)Enveloped viruses have a phospholipid membrane outside their capsid, whereas nonenveloped viruses do not have a phospholipid membrane.
• D)Both types of viruses have a capsid and phospholipid membrane; but in the nonenveloped virus the genetic material is between these two membranes, while in the enveloped virus the genetic material is inside both membranes.
• E)Enveloped viruses are enclosed in a single phospholipid layer (not a bilayer), nonenveloped viruses do not have this envelope.
