摘要：

In eukaryotes, condensing chromosomal DNA into heterochromatin is important for gene silencing and proper chromosome segregation. A recent study suggests a function for heterochromatin in protecting highly repeated genes and satellite DNA against excision caused by recombination or by joining of free DNA ends following DNA damage.
