Not so knotty genomes

Erez Lieberman, of the HST Bioinformatics and Integrative Genomics program has just published a provocative paper which uses moderate resolution mapping (1 megabase) of the 3 dimensional structure of the genome. The results are consistent with prior work suggesting that DNA maintains its function by packaging itself into a structure that is free of knots. Now, if I could only apply this to my collection of wires in my drawer.
