  Abstract

Cellular memory is defined as a long-term maintenance of a particular pattern of gene expression through many rounds of cell division or even after cell division. It is critical for development and differentiation of multicellular organisms. Chromatin dynamics including histone modification, histone replacement and chromatin remodeling play key roles in cellular memory.

Key Words: Pc group, trx group, position effect variegation, heterochromatin, histone H3.3
