Dynamics of DNA methylation during development
1 Nov 1993
Abstract excerpt
DNA methylation plays a role in the repression of gene expression in animal cells. In the mouse preimplantation embryo, most genes are unmethylated but a wave of de novo methylation prior to gastrulation generates a bimodal pattern characterized by unmethylated CpG island-containing housekeeping genes and fully modified tissue-specific genes. Demethylation of individual genes then takes place during cell type...
