Before too much time goes by, I need to apologize to this forum: both someone at longs.lance.colostate.edu and Kevin_P_McCarty@cup.portal.com have pointed out (one referring to Mandelbrot's book) that both the circulatory and pulmonary system have fractal characteristics. I should have limited myself to Mr. Mitchell's statement on possible fractal encoding of genetic information and that the human genome was small. In the interim, I asked a local (UCSD) researcher about the size of the human genome: offhand number he gave me was 10^14 base pairs, but don't quote him (so I haven't). I'd thought it was big (> 10^9), but ... >whew< 'Nuff said. -- /---------------------------------------+-------------------------------------\ | Bob Seegmiller | ..................... | | "Till mermaids wake us..." - Eliot | ..................... | | UUCP: ...!nosc!spectra!bseeg | ..................... |
