Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

Professor Asaf Hellman and his research team at the Hebrew University-Hadassah Medical School have unveiled new findings in the realm of methylation-directed regulatory networks. Their study sheds ...

Cars patched up after a wreck may look fixed—but never run quite as before. The same may hold true for chromatin, according to a study published in Science on November 6. In response to double-strand ...
