Scientist, May/June, 2000, "Unlike the
macro
world of engineering for example where materials and construction depends
upon gravity, material strength, etc., the ultra micro nano.molecular
world is dominated by the effect of thermal motions on the atomic
interactions within and between molecules. Molecules are endowed with kinetic
energy proportional to the temperature, which manifests
as translational.(like
one marble hitting another one causing it to move),
rotational and vibrational motion."
"Our central nervous system
contains from 10 to 100 million cells, each one of which has a storage
capacity equal to that of a large computer."....Alexander
Rich, American Biologist
and Biophysicist.
Each of our
nervous systems.(really,
just different functions of one).are
marvels in integrated
design.
"There is a balance within
this molecular world where the forces holding molecules together are vying
with the movement forces." For biological
self-assembly the physicist H.R. Crane noted."For
a high degree of specificity
the contact or combining spots on the two
particles
must be multiple and weak.".If
only a few strong connections are used, a chance would exist that the protein
may find a similair contact with improper proteins. A
safety factor is inherent.
Creator-God knows what He's doing. Each fit is unique.
"Most proteins are oligomeric.(composed
of multiple copies of one or more types of subunits).and
must
also have specific geometrical arrangement which is perfectly complimentary
to the arrangement on the other. The symmetry
is astoundingly
beautiful when seen under a microscope.(pictures
are in the article mentioned at the top of this page)."
In addition and for example,
Enolase, an enzyme
involved in the breakdown of sugar, relies upon a complimentary shape and
a specific collection of many weaker connections to ensure its
unique
function. Allosteric.'calipers'
measure the repeat length of DNA.
How
do these molecules have such intelligence to assemble themselves? Proteins
are created as unstructured, linear chains of amino
acids that must fold into a stable, functional conformation. Not only
must the protein be functional in its active conformation, but the protein
chain must also be designed to fold into this active conformation
using
only the folding tools available within the cell.
Present nanotechnology
involves utilization of rigid
structures and as such is not in a comparable category
with the marvelous system of self-assembly and flexibility that shows forth
the great light years ahead mind of He who has set up the ways man learns
from daily.
Cellular structure allows
amazing flexibility. The cell senses nutrients by a detection system which
responds to chemical signals given off by the nutrients.(like
you smell the food). It then can alter
its structure opening up to absorb the nutrients.
Many genes are never turned
on or copied into mRNA, once embryonic
development is complete. Once an
embryo
divides, it follows distinct mathematical patterns as determined by the
laws of physics. Where the parts go after cell
division evidences mathematical features.."The
patterns in which cells divide.(their
cleavage patterns).display
a wide range of geometries...including approximate symmetry...cleavage
occurs alternately in two directions; first a vertical split into two cells;
then another vertical one.(in
a plane at right
angels to the first).into
4, then a horizontal one into eight, then a vertical one into 16 and so
on...There is a single, universal mathematical mechanism and that mechanism
has a standard catalog or preferred patterns including target patterns,
spirals and the spherical patterns of cleavage."....Ian

'Junk' DNA:.Science
News, Volume 164, number 24, December 10, 1994 'Does nonsense DNA speak
its own dialect?' reported extremely significant results of genetic research
citing
the December 5, 1994 issue of.Physical
Review Letters.containing
research by molecular biologists at Harvard Medical School and physicists
at Boston University strongly indicating that so called 'junk' DNA is not
junk after all. Their study of 37 DNA sequences containing 50,000 base
pairs from a variety of organisms showed that the 'junk' DNA, amounting
to 90% of the human genome,
is actually written in
a special language, for a reason.
Their tests showed 'language like properties' in the 'junk' DNA indicating
it to be distinctly different from the code of the genes. It has been wondered
just where in the genome are the instructions that tell the genes when
to express and when not to, so that, for example, you get ears on the sides
of your face and not coming out the back of the neck. It has been discovered
that this 'junk' DNA is actually an
'aerial'.
DNA is not junk. None of
it. Creator-God makes no mistakes. The original created patterns are perfect,
including the natures we were made with and made that way for
a reason.
DNA is
far more complex
than the simplistic picture of it that you may have seen. It really involves
a coil within a coil and from there it really gets complicated.
We won't get into that here at all. But, if you want to, an explanation
of DNA's knotting and linking is on pages 50-72 in.Life's
Other Secret. And why the coil?
DNA can be pulled apart but
bounces back into shape. And with this feature of DNA the mathematical
principle of topology discovered by Henri
Poincaré, is noticed.
It's only when enzymes
cut DNA strands apart can they later reassemble them. But some wisdomless
'scientists' become enthralled
attempting God's abilities with their genetic
modification techniques.
