Two paths to silence merge
Article Abstract:
Cellular memory is thought to be regulated by two 'epigenetic mechanisms, which heritably change the characteristics of the cell without altering its DNA sequence. One mechanism involves a group of enzymes that attach methyl groups to the DNA, the DNA methyltransferases, and the other involves Polycomb group proteins around which the DNA is wrapped.

Rival genetics projects build bridges
Article Abstract:
A meeting was held to mend fences and build bridges between the two projects, the Tree of Life project and the Consortium for the Barcode of Life Initiative using short DNA signatures. The meeting would help the two groups to collaborate and share their ideas and information to find common focus rather than oppose each other.

Perceptions of epigenetics
Article Abstract:
The interpretation of epigenetic phenomena and a revised definition that embodies contemporary usage of the word are presented. Epigenetic events can be defined as the structural adaptation of chromosomal regions so as to register, signal or perpetuate altered activity states.
