GO biological process ontology term - GO:0031507 - heterochromatin formation

Term summary

ID
GO:0031507
Name
heterochromatin formation
Ontology or CV name
GO biological process
Definition
An epigenetic gene silencing mechanism in which chromatin is compacted into heterochromatin, resulting in a chromatin conformation refractory to transcription. This process starts with heterochromatin nucleation, its spreading, and ends with heterochromatin boundary formation.
