In
the
instance
of

there
also
 similarities?

will
each
amino
acid
 differ?
 
 xi)

the
differences
between
the
structural
levels
of
proteins
as
well
as
key
 structures
that
can
be
identified
certain
levels.
 
 xii)

What
is
the
process
called
wherein
a
protein
is
unfolded?

What
effect
does
this
 have
on
the
protein?
 
 xiii)

Know
the
three
components
that
make
up
a
nucleic
acid
 
 xiv)

Understand
the
difference,
structurally,
between
purines
and
pyrimidines.
 xv)

What
purine
pairs
up
with
what
pyrimidine?

What
kind
of
bond
do
they
form?
 
 xvi)

Be
able
to
identify
DNA
or
RNA
based
upon
the
sugar
found
in
the
molecule.
 
 
 A
Tour
of
the
Cell
 
 i)
Why
is
it
more
beneficial
for
cells
to
be
smaller
rather
than
larger?

How
does
it
help
the
other
 systems
of
the
cell
to
perform
their
respective
functions?
 
 viii)
What
is
