DNA weighing many times more than the entire earth needed
(Facts About Evolution)
means 1 x 10 89190 DNA molecules, on the average, must form to provide the one chance of forming the specific DNA sequence necessary to code the 124 proteins. 10 89190 DNAs would weigh 10 89147 times more ...

No probability of randomly forming DNA
(Facts About Evolution)
Based on probability factors . . any viable DNA strand having over 84 nucleotides cannot be the result of haphazard mutations. At that stage, the probabilities are 1 in 4.8 x 10 50 . Such a number, if written out, would read: 480,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. "Mathematicians agree ...

Nucleotide count of several organisms
(Facts About Evolution)
1) There are 5,375 nucleotides in the DNA of an extremely small bacterial virus (thetax174). (2) There are about 3 million nucleotides in a single cell bacteria. (3) There are more than 16,000 nucleotides in a human mitochondrial DNA molecule. (4) There are approximately 3 ...

Chance for random formation of a gene to control a medium sized protein
(Facts About Evolution)
Now we know that the cell itself is far more complex than we had imagined. It includes thousands of functioning enzymes, each one of them a complex machine itself. Furthermore, each enzyme comes into being in response to a gene, a strand ...

DNA follows instructions with switching
(Facts About Evolution)
bacteria, for example, Jacob and Monod demonstrated a control system that operates by switching off 'repressor' molecules, i.e., unmasking DNA at the correct 'line number' to read off the correct (polypeptide) subroutines. With eukaryotes \a common type of bacteria\, Britten and Davidson have ...

Living cells store and operate on information like tiny computers
(Facts About Evolution)
All this is strikingly similar to the situation in the living cell. For discs or tapes substitute DNA; for 'words' substitute genes; and for 'bits' (a bit is an electronic representation of 'yes' or 'no') substitute the bases adenine, thymine, guanine and cytosine."— \ Fred Hoyle and C. Wickramasinghe, Evolution ...

The Amazing Story of Messenger RNA
(Facts About Evolution)
code in the gene (which is DNA, of course) is used to construct a messenger RNA molecule in which is encoded the message necessary to determine the specific amino acid sequence of the protein. "The cell must synthesize the subunits (nucleotides) for the RNA (after first synthesizing the subunits ...

Five steps needed for evolution are little more than armchair guessing and hopefulness
(Facts About Evolution)
Evolution Model for the Origin of Life on the Earth: According to the evolution model, the story of life on the earth began some five billion years ago and gradually unfolded through a series of five stages: Stage 1 Evolutionists have imagined that the atmosphere of the early ...

Scientists admit origin of life seems to be a miracle
(Facts About Evolution)
An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle."—Francis Crick, Life Itself, Its Origin and Nature (1981), p. 88 ...
