Euchromatin, being less compact, is more accessible to the proteins which drive gene expression. Heterochromatin, on the other hand, is not accessible because of its condesnsed methylated state.

Chromatin: Uncoiled, non-condensed piece of DNA (unlike chromosome which are highly condensed) along with the associated histone and non-histone proteins.

There are two types:

1. Euchromatin: which is a partially or fully uncoiled piece of DNA which is genetically active, other-words active in transcription. Found in BOTH eukarytoes and prokaryotes. In this state they stain little with dyes

2. Heterochromatin: is a state where the chromatin is tightly coiled, hence it stain darker with dyes. It is not available for the RNA polymerase to transcribe it. Generally these are genes that are not expressed in that cell type or inactive satellite sequences, telomers, etc. Heterochromatin is usually localized to the periphery of the nucleus.
