DNA is a molecule, which has an extremely complex structure. This molecule contains the complete information of the human body, which is recorded by means of a special coding system. In addition to features like height, eye, hair and skin colours, the DNA of a single cell also contains the design of 206 bones, 600 muscles, a network of 10,000 auditory muscles, a network of 2 million optic nerves, 100 billion nerve cells and 100 trillion cells in the body. If we were to write down the information coded in the DNA, we would end up with a giant library consisting of 900 volumes of encyclopaedias of 500 pages each. Yet this incredibly voluminous information is not encoded in volumes of encyclopaedias, but in the components of DNA called "genes".
Genes are made up of four special bases called nucleotides, which occur in a particular sequence. An error in this sequence would render the gene completely useless. There are 200,000 genes in the human body, and each of the millions of nucleotides making up these genes must be in the right sequence. When mathematical calculations are done to measure the probability of this sequence being formed by chance, its impossibility becomes evident. For example according to the calculations of Frank Salisbury, an evolutionist biologist, the possibility is one in 41,000. The number 41,000 is the equivalent of 10600, which gives the figure 1 followed by 600 zeros! This number is completely beyond our comprehension.
The impossibility of the formation of RNA and DNA by a coincidental accumulation of nucleotides is expressed by the French scientist Paul Auger in the following way:
We have to sharply distinguish the two stages in the chance formation of complex molecules such as nucleotides by chemical events. The production of nucleotides one by one-which is possible-and the combination of these within very special sequences. The second is absolutely impossible.
