Definition of Euchromatin

Euchromatin is that region of the chromosome that is less intact and less condensed. The chromatin is the genetic material present in the chromosome and it has two types i.e. heterochromatin and euchromatin. The prokaryotes like bacteria have only euchromatin present in them. It is generally an active portion of a chromosome.


It has structural genes present in it and the polymerases are fully allowed to access it. Hence, the processes of transcription and translation proceed. The housekeeping genes are also present in this euchromatin as they are necessary for the survival of the cell. It is packed loosely hence when it is stained with a dye, it gets stained lightly.
