leading four three eukaryotic prokaryotic somatic 20 gametes nucleotide nucleoside lagging
In
cells
,
a
genome
consists
of
a
single
DNA
molecule
.
There
are
amino
acids
,
but
there
are
only
nucleotide
bases
in
DNA
.
A
is
formed
by
a
sugar
and
a
nitrogenous
base
.
The
strand
is
synthesized
as
a
series
of
segments
called
Okazaki
fragments
.
A
chromosome
has
hundreds
or
even
thousands
of
replication
origins
.
A
codon
consists
of
nucleotide
bases
.
Human
are
reproductive
cells
.
In
the
strand
only
one
primer
is
required
.
Human
cells
are
the
non
-
reproductive
cells
.
A
consists
of
a
nitrogenous
base
,
a
sugar
and
a
phosphate
group
.
