I got me one a them gol durned booky things and I is a readin it. But I found a problem here so I know that a smart fella like you will have the answer. I was aware that it takes DNA to produce DNA so the whole thingy about the wild proteins from outer space that caused life on this planet is a bit confusing to me. Regardless, I find this type of superstitious babbling quite interesting. Never the less, I think my story of how life began (previous post) is more fun to read. This stuff makes me wonder just exactly how long that first protein would have had to live to replicate itself. Good thing that "nature" provided meals for it while it was deciding what it wanted to evolve into.
Here is part of an article. Naturally a simple denial of the fact that the first life form had to have a complicated DNA chain to produce DNA will suffice. (Needed to reproduce itself)
Experiments Show Functional Proteins To Be Extremely Rare
Among The Possible Combinations
So, what are the chances (probabilities) that a never-before-seen functional (folding) protein-type would result from such a mutation-driven random "search"?
--Experimental work using actual folding proteins from living things, indicates that more than
99.999999999999999999999999999999999999999999999999999999999999 percent of the possible combinations of randomly ordered amino acids would result in non-folding, useless junk chains. They would be non-functional for actual proteins which could build and comprise the structures in living cells.
--This is explained in the following article:
http://www.leaderu.com/orgs/fte/darwinism/chapter6.html
The above article refers to both the work of Dr. Hubert P. Yockey and the laboratory experiments of Dr. R.T. Sauer (MIT), who extensively analyzed the make-up of actual proteins from living cells. The work of these scientists does take into account that there is a small degree of interchangeability of a certain amino acid or two along the sequence of a protein, and the protein still being able to retain some function. ...However, this experimental evidence still indicates that functional classes of proteins are extremely rare among the possible chains of junk sequences that are most likely to assemble by chance. --Despite some amino acid interchangeability, the result of these experiments is that the odds of assembling (by random processes) one new functional protein (which properly folds), are about one chance in 1065. --- (1065 is the number one, with 65 zeros behind it, and is about the number of atoms in all the matter in an average galaxy.) So, the odds of one new functional protein assembling by the random chance processes, would be the equivalent of randomly finding one specific atom out of the galaxy.
This is sort of like saying that if there were a galaxy-sized ocean full of reproducing A-bacteria, that galaxy of baceria might produce one functional protein by means of random assembly of amino acids, while at the same time there would also be (on average) 1065 failed attempts or trials, which would be non-functional, junk amino acid chains. -- (A single "attempt" or trial would involve the random assembly of about 200 to 700 hundred amino acids into a chain. It is as if each atom in the galaxy represents "a trial" of randomly putting together a chain of 200 to 700 amino acids.) -- So, the research demonstrates that almost all attempts would be non-functional for life (because they don't fold properly) and useless for the construction and function of living things. If this galaxy-sized mass of trash-sequences of amino acids were to stay assembled for a certain length of time, they would (during that time) clog up all the A-bacteria cells and obstruct that one functional protein from getting together with any other new functional protein a galaxy distant away. --Thus, any one functional protein that might hypothetically form would be isolated and lost in galaxy-sized ocean of non-functional, useless amino acid chains.
-- So, if the earth and every other planet in our solar system were filled entirely with reproducing A-bacteria, we would expect there to be basically ZERO chance that even one novel and new functional protein would randomly assemble.
...and we would expect basically those same odds even if there were A-bacteria reproducing on a hundred billion earth-like planets in the galaxy.
...We might somewhat possibly expect one single functional protein to form in a galaxy if every planet, star and body in it were filled with A-bacteria.
--But in one galaxy, we would not expect a second novel functional protein to randomly assemble in order to begin to build something like a flagellum.
--In all the matter in a galaxy, we would not expect the required DNA code for the assembly of even 2 of the 40 new flagellum-construction proteins to occur in one of the A-bacteria by random processes. But even if 2 new proteins were coded for and built inside an A-bacteria cell, this is not close to the 40 required for a flagellum. With only 2 new proteins, there would be no flagellar function, and so this would not give the A-bacterium a darwinian "advantage" for better survival. In fact, it is more likely that the 2 proteins (having as yet no function) would merely clog up the "works" of the cell, and confer a disadvantage on the organism.
Much worse: The new DNA flagellar assembly instructions (which cause the cell to assemble those 40 proteins) have not even been considered yet, ...and those instructions are probably just as complicated as the 40 proteins that go into the flagellum. The new assembly instructions in the DNA would have to develop at the very same time as the new coding for building the 40 proteins.
NOTE: You can try your own hand at intelligently designing a properly folding protein at the following web site:
http://fold.it/portal/info/science
(And if any of your amino acid chains do not properly fold into a discrete shape,
they are then examples of a non-functional chains which cannot be an actual protein.)
Probabilities Spelled Out Further
In this "WorldView Site", I have an article entitled "A Mathematical Proof of Intelligent Design in Nature." It addresses the statistical odds of the random protein-building situation just spoken about. --Please read it, if you have not already.
