Chromatin


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.
