All human beings have fundamentally the same anatomical structure and operate through the same bio-chemical and physiological processes and are driven by similar biological urges. Yet no two human beings are alike. What is more important is that any individual living now is entirely different from anyone who has ever lived in the past or will live in future. Each person is unique, unprecedented and unrepeatable. Leonardo do Vince the great sculptor, painter, philosopher all rolled into a great creative genius was the so-called illegitimate son of a half witted woman who spent a night with an itinerant soldier at the wayside inn. That was the clicking of the genes. The biological mechanisms through which each person develops his own behavioural singularity are two fold—the evolution part and genetic endowment. [111]
There is now overwhelming evidence that man's body and brain have not changed significantly during the past 10,000 years. The same set of genes that governed man's life when he was Paleolithic hunter or a Neolithic former still governs his anatomical development, physiological needs and emotional drives.[112]
Any stretch of DNA has two strands and therefore the capacity for holding two different sequences of bases, depending on which strand is read. That is not to say though that both strands are not used. Some genes will be on one stand while others will be of the other strand. Therefore, varied terms have been coined to refer to the strand, which hold sequence information and those which do not, such as sense and anti-sense, coding and non-coding. A gene sequence is always read from the 3' end to 5' end, and therefore genes, which reside on different strands are read in opposite directions, again a fact that needs consideration when a researcher is trying to decipher the gene sequence.
