Vidqun: So let me get this straight. DNA/RNA is
not an information system and DNA doesn't qualify as code.
Viv: Right.
So,
DNA/RNA complex is not an information system. DNA code does not qualify as “information.”
Is that right? Follow with me:
Ribonucleic
acid, or RNA is one of the three major biological macromolecules that are
essential for all known forms of life (along with DNA and proteins). A central tenet
of molecular biology states that the flow of genetic information in a cell is
from DNA through RNA to proteins: “DNA makes RNA makes protein”. Proteins are
the workhorses of the cell; they play leading roles in the cell as enzymes, as
structural components, and in cell signaling, to name just a few. DNA (deoxyribonucleic
acid) is considered the “blueprint” of the cell; it carries all of the genetic
information required for the cell to grow, to take in nutrients, and to
propagate. RNA–in this role–is the “DNA photocopy” of the cell. When the cell
needs to produce a certain protein, it activates the protein’s gene–the portion
of DNA that codes for that protein–and produces multiple copies of that piece
of DNA in the form of messenger RNA, or mRNA. The multiple copies of mRNA are
then used to translate the genetic code into protein through the action of the
cell’s protein manufacturing machinery, the ribosomes. Thus, RNA expands the
quantity of a given protein that can be made at one time from one given gene,
and it provides an important control point for regulating when and how much protein
gets made. For many years RNA was believed to have only three major roles in
the cell–as a DNA photocopy (mRNA), as a coupler between the genetic code and
the protein building blocks (tRNA), and as a structural component of ribosomes
(rRNA). In recent years, however, we have begun to realize that the roles
adopted by RNA are much broader and much more interesting. We now know that RNA
can also act as enzymes (called ribozomes) to speed chemical reactions. In a
number of clinically important viruses RNA, rather than DNA, carries the viral
genetic information. RNA also plays an important role in regulating cellular
processes–from cell division, differentiation and growth to cell aging and
death. Defects in certain RNAs or the regulation of RNAs have been implicated
in a number of important human diseases, including heart disease, some cancers,
stroke and many others (cursive script added).

From the above I discern some serious information flows back and forth. So it's not only one way traffic, the information flows both ways. Think
of it as a factory. The sender of the information, the CEO, is the DNA, right? Next, we
have the transcription process with the m-RNA, the workhorse. The first recipient benefitting
from this process would be the cell because of the manufacture of structural
proteins, amongst other things. The second recipient, benefitting from the
information, would be the organism that are kept alive by these processes. To
sum up: Genetic information is locked up in the nucleus. This is unlocked and transcribed
by RNA, which in turn is responsible for the manufacture of proteins for a
specific purpose (e.g., hormones). These are passed from the cell to the
organism. If something goes wrong with these processes, the organism dies. The factory goes out of business.
Vidqun:
It developed spontaneously, by itself, from basic elements in solid and liquid
form.
Viv:
Wrong.
Would you care to elaborate. How do you think DNA developed? By accident? Perhaps a better answer would be, I don´t know.
Viv,
"it" is a mystery. I would love to know what "it" is, then
I might also be able to understand the concept of evolution. No, jokes aside, “it”
is referring to DNA. I thought that was obvious. Anyway, according to Cofty
it's electrons driving the production and function of DNA and RNA. I call those
"super intelligent" electrons. What would you call them?
Orphan
Crow, what happened here was a huge experiment. A lot of life forms have come
and gone. All in preparation for the crown of creation, man, which was a massive failure in the end. The human race cannot even work out their origin. They came up with the theory of evolution to avoid taking responsibility for their actions. I would venture a guess that God would have been very disappointed. That's why he said the following:
"The nations were enraged, but your wrath has come, and the time has come for the dead to be judged, and the time has come to give to your servants, the prophets, their reward, as well as to the saints and to those who revere your name, both small and great, and the time has come to destroy those who destroy the earth." (Rev. 11:18 NET)
