Accession:GO:0031052 term browser browse the term
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.
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.
Synonyms:exact_synonym: establishment or maintenance of heterochromatin architecture
