Causes of DNA twisting

Hi Folks!

The report about the twisted DNA of copperhead snakes
as posted at;

http://www.keelynet.com/interact/Arc_1_98-7_98/00001054.htm

comes into question when reading this file;

http://www.aip.org/enews/physnews/1998/split/pnu359-3.htm

MOLECULAR INDIVIDUALISM, the idea that physically
identical molecules can behave differently under
seemingly identical conditions, has been observed by a
Stanford group (Steven Chu, 415-723-3571).

Inside a microscopic fluid cell, coiled DNA strands
experiencing the same flow currents unravel in a host
of radically different ways--sometimes forming kinks
in the middle, others forming knots at one or both
ends, and others getting caught up in a folded shape
as they try to unfold.

Speaking at the AAAS meeting, Chu attributes this
(non-chaotic) phenomenon to tiny fluctuations in the
starting conditions--such as a small temperature
change in the fluid cell.

(Stanford news release, February 11, 1998.)
----------------
Does anyone have a copy of the report by the
researcher at Glen Rose? These were supposed to have
been long term exposures which would have involved
numerour replications of the tissue subject to the
extant environment so maybe there are different
criteria involved...
