# s-gene: epigenetic 'cis' and 'trans' memories

<< How epigenetic memory is stored and inherited is an on-going debate (..). In so-called  ‘cis  memory’, epigenetic information is proposed to be physically stored in local chromatin states that are associated, for example, with DNA methylation or histone modifications. By contrast, in  ‘trans  memory’, epigenetic information is stored in the concentration of a diffusible factor such as a transcriptional repressor. >>
