BIOD 171 MODULE 6 QUESTIONS AND
ANSWERS WITH COMPLETE
SOLUTIONS 100% CORRECT RATED A+
True or False: Because the genome is contained within an enclosed space
(much like the nucleus of a cell), viruses are classified as eukaryotic.
✔✔False — Viruses are not made of cells and do not have a true nucleus, so they
are not classified as eukaryotic.
True or False: Although viruses may contain their genome within an enclosed
space (much like the nucleus of a cell), it is considered neither eukaryotic nor
prokaryotic.
✔✔True — Viruses are acellular and do not belong to either group.
Describe the two basic components of a virus.
✔✔A virus consists of genetic material (DNA or RNA) and a capsid, which is a
protein shell that protects the genome.
True or False: You would expect to see a viral envelope on a virus infecting a
bacterial cell.
✔✔False — Most bacteriophages (viruses that infect bacteria) do not have an
envelope.
The overwhelming majority of animal viruses are enveloped, whereas the
majority of plant or bacteria-infecting viruses are not.
✔✔True — Animal viruses often have envelopes; plant and bacterial viruses
typically do not.
, The envelope surrounds the ________ of some viruses.
✔✔Capsid
The ________ surrounds the capsid of some viruses.
