I have been trying to relate the
genetic code to a particular number system and would welcome any assist=

the four bases somehow correspond consistently with digits in ternary o=

quarternary number systems?

=A0 =A0 =A0I conjecture that the triplet code in DNA has been optimized b=
y
evolution for efficiency of computation. Certain computer languages
(software environments) have been developed to take advantage of the
extra computing efficiency represented by a base 3 coding of numbers
rather than a base 2 coding of numbers.
=A0 =A0 =A0Although the development of an organism is not literally
"computing," I do think the process has some features analogous to
computing. In a very general sense, developing an organism from its
genetic code is a bit like computing. The efficiency of a base 3
representation of numbers may be more efficient in than the binary
base, or any other base, in both computing and ontology.
=A0 =A0 =A0The following link reviews the reasons why a base 3 system is
sometimes more efficient than a base 2 system.http://www.americanscientis=

=A0 =A0 If this conjecture is true, it suggests that early in the history
of biology some organisms used a different base. There may have been
several different bases for different organisms. Survival of the
fittest chose the most efficient way to represent genetic information.
I would be interested if anyone knows of a bacteria that codes by any
means other than base triplets. There may be some organism in some
extreme environment that hasn't evolved for a long time, so keeps a
base 2 (or base 10!) code. If humans really do find extraterrestrial
life, it would be interesting to see if their genetic information is
coded in triplets. If this conjecture is true, one should see base
triplets where ever life has had time to evolve.
=A0 =A0 However, it may just be coincidence. Base 3 just popped up in the
first orgnaism, that didn't give the other organisms a chance |:-)
Sort of a pioneer effect. The individuals in an isolated community
tend to look like the early pioneers.

Is this the correct link?
