Author Topic:   Junk DNA introns are actually fractals used as "building construction blueprints"?

Just browsing around Slashdot, I found an interesting article-
http://www.sfgate.com/cgi-bin/article.cgi?file=/gate/arch...
quote:
Rather than being useless evolutionary debris, he says, the mysteriously repetitive but not identical strands of genetic material are in reality building instructions organized in a special type of pattern known as a fractal. It's this pattern of fractal instructions, he says, that tells genes what they must do in order to form living tissue, everything from the wings of a fly to the entire body of a full-grown human.
Another way to describe the idea: The genes we know about today, Pellionisz says, can be thought of as something similar to machines that make bricks (proteins, in the case of genes), with certain junk-DNA sections providing a blueprint for the different ways those proteins are assembled.
It's not a new idea, as
R Roman-Roldan, P Bernaola-Galvan, J. L. Olivier, "Sequence compositional complexity of DNA through an entropic segmentation method." Physical Review Letters, V80, p1344 (1998) is a previous article on the idea.
"The analysis of sequence correlation structure, in both the spatial and the frequency domains, resulted in the finding of short range[1] and long-range[2] correlations in nucleotide sequences, thus uncovering a complex fractal structure of DNA."
and even before that,
CA Chatzidimitriou-Dreismann, RMF Streffer, D Larhammar (1994), "Are there any fractals in DNA of living organisms"
RF Voss (1994), "Long-range fractal correlations in DNA introns and exons", Fractals, 2(1):1-6.
Maybe this would be useful in PB's multipurpose genome theory?

Yes, I saw that article. Seems somewhat rational, but I can't help but think that what /. people are saying is true as well. If this guy can figure it out, that'd be great -- VERY great and it'd very beautifully explaining some things -- but until he does, I don't think anyone will take him seriously.
Also, that article seemed a bit untechnical... but that's to be expected.
