Which of the following descriptions correctly identifies the main structural differences between viruses with envelopes and viruses without envelopes?
A) Viruses with envelopes have their genetic material enclosed by a layer made only of protein.
B) Viruses without envelopes have only a phospholipid membrane, while viruses with envelopes have two membranes, the other one being a protein capsid.
C) Viruses with envelopes have a phospholipid membrane outside their capsid, whereas viruses without envelopes do not have a phospholipid membrane.
D) Both types of viruses have a capsid and phospholipid membrane; but in the viruses without envelopes, the genetic material is between these two membranes, while in the viruses with envelopes the genetic material is inside both membranes.

Question

Quizplus · Accepted Answer

Viruses with envelopes have a phospholipid membrane outside their capsid, whereas viruses without envelopes do not have a phospholipid membrane. Option A is incorrect because viruses with envelopes have a phospholipid membrane as well as a layer of protein around their genetic material. Option B is incorrect because viruses without envelopes do not have any membrane, and those with envelopes have only one membrane, which is a phospholipid membrane. Option D is incorrect because viruses without envelopes do not have a phospholipid membrane.
