Bansal, Manju (1999) DNA structure: Yet another avatar? In: Current Science, 76 (9). pp. 1178-1181.
Everytime the story of DNA structure seems to reach a conclusion, it bounces back to centre stage by appearing in yet another incarnation. The latest avatar to manifest itself is a stretched and overwound form of DNA reported recently by a French group-1, working with single DNA molecules. When a moderately large stretching force (of about 3 pico Newtons) is applied, the DNA molecule apparently becomes highly twisted and extended, but even more amazingly it takes up an inside-out structure in which the phosphodiester chain is on the inside and the bases are exposed.
