Project description:The timing of DNA replication is an important developmentally regulated regional property that is correlated with gene expression, chromatin state, GC content, subnuclear structure. These correlations reflect the variable accessibility of origins to a limited pool of initiation factors within different context, and the extent to which changes in replication timing occur during differentiation. Therefore, temporal order of genome replication could be sufficient to identify the cell type. A lot of studies for characterizing DNA replication have been done using many different types of cells, however, the pattern of it in the totipotent cells is still entirely unknown. In this study, we try to understand the molecular basis underlying totipotency by identifying specific DNA replication features found exclusively in totipotent cells.
