mikael writes "Sciencedaily.com is reporting that scientists have discovered how DNA is folded within the nucleus of a cell such that active genes remain accessible without becoming tangled. The first observation is that genes are actually stored in two locations. The first location acts as a cache where all active genes are kept. The second location is a denser storage area where inactive genes are kept. The second observation is that all genes are stored as fractal globules, which allows genes that are used together to be adjacent to each other when folded, even though they may be far apart when unfolded."
