It is a
complex of genetic material (DNA and RNA) associated protein (histone) located
in the cell nucleus and condenses during cell division in order to form
chromosomes.
There are
two states of chromatin organization:
-
Euchromatin: slightly condensed chromatin. It is this state which is the cell
nucleus and has enhanced activity because of its easy genetic manipulation.
-
Heterochromatin: highly condensed chromatin. This is the state that is when the
cell does not want particular gene is expressed, thereby reducing its genetic
activity.
