Term Information [More information on chromosome breakage]

Accession
GO:0031052
Name
chromosome breakage
Ontology
biological_process
Synonyms
establishment or maintenance of heterochromatin architecture
Definition
Regulated cleavage of the developing macronuclear genome at a limited number of chromosome breakage sites (CBS). The macronuclear destined segment (MDS) sequence adjacent to the CBS (or separated from it by a BES) receives a macronuclear telomere following chromosome breakage. Source: GOC:ns
Comment
Note that this term refers to breakage of chromosomes during normal DNA rearrangements characteristic of ciliates; it is not to be used for DNA damage or other abnormal occurrences.
