Chromatin is uncondensed DNA,
the typical morphology in
interphase ( phase of the cycle in
which cells isnot dividing ). In
this phase the cell cycle
can befound as , more
condensed and (in electronic
microscopy) of DNA molecules,
as euchromatin, less and
lighter portions DNA molecules.

Since is uncondensed the
is the biologically portion of the
, i.e., the region has active
genes be transcripted into .The
heterochromatin represents the
portions of the molecule.
