Nucleoplasm
Similar
to
the
cytoplasm
of
a
cell,
the
nucleus
contains
nucleoplasm
-
a
highly
viscous
solid
containing
the
chromosomes
and
nucleoli.
Chromosomes
contain
information
encoded
in
DNA
attached
to
proteins
called
histones
and
are
usually
arranged
in
to
a
dense
network
called
chromatin.
Nucleoli
are
granular
structures
which
make
ribonucleic
DNA
(rDNA)
and
assemble
it
with
proteins.
