First molecular simulation of a long DNA strand shows unexpected flexibility

It turns out that sequencing the human genome – determining the order of DNA building blocks -- has not completely cracked the code of how DNA directs various cellular processes. In addition to the sequence of the base pairs, the instructions are in the packaging – how DNA is folded within a cell.
