Navigating the Nucleosome Uncovering genomic instructions for how DNA is packaged reveals a new dimension of the genetic code.

The eukaryotic genome can be up to 130 billion base pairs long, but required to fit inside each cell nucleus. To do this, DNA is tightly wrapped around histone proteins in bead-like clusters. Each cluster is called a nucleosome. For years, mapping experiments had revealed that nucleosomes favored particular DNA sequences, reflecting the ability of certain DNA sequences to bend more sharply and wrap around histones. Still, whether such preferences actually meant DNA coded for the positions of nucleosomes in vivo was unclear.

Wow.. i never tought I'm gonna read my name on this sites.. I feel hoerond. Anyway, there already is some sort of gui to design bacteria : also fatured in a , it seems pretty drag-and-drop designing your microbe basing on predefined modules.But it would be nice to have a possibility to actually write a program without being bound to this gui/modules. Creating a DNA programming language shure would be a fun thing! Maybe someone could extend the idea to write some sort of genetic operating system , so that coding dna could be even simpler and much more fun. Ican already hear the geeks trying to port Linux on Microbes ;D
