3. All
of
the
following
are
true
statements
about
how
viruses
differ
from
cells,
except
one.
Which
statement
is
NOT
true?
a. Viruses
are
unable
to
reproduce
independent
of
a
host
cell,
but
all
cells
can.
b. Viruses
cannot
be
observed
using
a
light
microscope,
cells
usually
can.
c. Many
viruses
utilize
RNA
as
their
genetic
material,
cells
don’t.
d. Viruses
do
not
contain
large
organized
enzyme
assembly
centers
like
ribosomes
to
manufacture
proteins,
cells
do.
e. Viruses
are
unable
to
produce
their
own
macromolecules
or
provide
a
cellular
energy
source
without
a
host
cell,
cells
usually
can.
