These patterns of gene expression are governed by the cellular material - the epigenome - that sits on top of the genome, just outside it (hence the prefix epi -, which means above).
基因表达模式(patterns of gene expression)受细胞物质外基因所控。外基因，高于基因，通俗点说，基因之外(前缀epi -，意即上面)。

Cellular aging is linked to deficiencies in efficient repair of DNA double strand breaks and authentic genome maintenance at the chromatin level.
