摘要: The methylation state of DNA can be transferred from generation to cells, qualifying this gene-regulatory event as epigenetic. In his Perspective, Baylin discusses the new link between replication and methylation, demonstrated in week's issue, speculates that linkage is disrupted tumor cells. On page [1996][1], Chuang et al . suggest are linked through binding DNA-methyltransferase proliferating cell nuclear antigen (PCNA). [1]: http://www.sciencemag.org/cgi/content/short/277/5334/1996
