The Real
Decoded Genome:
3% of the DNA does the job; the rest is just ŌjunkÕ
~ A T Mann
Despite the
claims of an ultimate "decoding of the human genome," a fantastic
opportunity to explore human nature and biology is being wasted
at the moment through the shortsightedness of science and scientists.
During the first
stage of the now complete Human Genome Project, scientists focused
on trying to identify the location of genes on a chromosome. Each
cell of the human body, except for sperm and egg cells, contains
23 pairs of chromosomes that are ordered on a long strand of DNA
wound tightly in the nucleus. If unwound, the strand would be about
6 feet long. The genes that regulate life, and that influence or
cause diseases, are arranged on chromosomes. But those genes make
up only about 3% of the strand of DNA.
Scientists do
not understand the function, if any, of the remaining 97% of the
DNA. Often referred to as "junk DNA," it most likely contains important
information, but scientists do not have the ideas, desire or technology
to explore it. This is ironic in the extreme because we know nature
is not wasteful, and the DNA molecule and its coding is thought
to be the most sophisticated development of life.
Are we to believe
that this most profound, complex mechanism of life itself is 97%
junk? With no purpose or meaning? I think not.
The recently
completed Human Genome ProjectÕs working draft contains information
on the 3% of the DNA that can currently be sequenced. Sequencing
is the process of breaking genes into their most basic components:
adenine, thymine, guanine and cystosine. These almost repetitive
components are called bases, and they are paired together, AÕs with
TÕs, CÕs with GÕs, on the double-helix structure of the DNA strand.
Their structure is like a spiral staircase: the AT and CG pairs
are the steps that link the two sides of the staircase.Just
as molecular genetics has apparently vindicated Darwinism, it has
also served to show that some aspects of evolution are much more
complex than Darwin imagined.
The scientific
perception is that the genomes of all complex organisms contain
huge amounts of repetitive and apparently useless DNA. Some of this
could be relict material (the slowly decaying hulks of once-useful
but now functionless genes); but some of it may be information whose
functions have yet to be discovered.
Studies at the
level of the genome show a surprising amount of genetic mobility,
sometimes between very remotely related species. This suggests that
we have still to discover some other process of genomic evolution
beyond DarwinÕs Theory of Evolution.
Could it be
that this junk DNA is a repository of our collective past, like
the "collective unconscious" posited by Carl Gustav Jung?
It may be that
we each contain a vast, untapped reservoir of information and the
mechanisms to utilize it that goes beyond our contemporary mechanist
materialist view of humanity?
Since mechanist-materialist
science only recognizes those genes directly connected with the
development and maintenance of the physical body, what if there
are genetic structures associated with emotions, mind, memory or
even spirit?
It may be that
we are only beginning to understand the common resources we carry
within every cell, and which are available to all conscious beings.
We can only
hope.
