ЁЯФ╢ The dominant influences in the formation of human personality are generally believed to be environment and enterprise. But this belief holds true only to a certain extent. It is a matter of common observation that children born and brought up in similar circumstances develop major mental and emotional differences later. This is primarily on account of the basic life-elements, which go to make the person of an offspring.
ЁЯФ╖ These subtle influences come down over many previous generations from both paternal and maternal sides. They combine to maintain the continuity of hereditary characteristics and also mutate in a strange way to spawn entirely new traits and identities, thereby taking evolution forward.
ЁЯФ╢ Scientists have been able to uncover the fundamental basis of life of not only human beings but of all the life forms belonging to animal and plant worlds. Since the second half of the 20th century, a great amount of research has been made in this direction and almost daily new findings are published. This rapid and profuse work is propelled by advances in electron microscopy and cybernetics in which information from different fields are collated and integrated into a composite whole.
ЁЯФ╖ All living organisms from the simplest amoeba to the most complex human body have been formed by the same life-chemical, the DNA or deoxyribonucleic acid. The DNA contains in chemically coded form - the blueprint of life, i.e., all the information needed to build, control and maintain a living organism. The DNA has extremely tiny spring-like structures, which can be seen through an electron microscope. The defined stretch of DNA is called genes. The genes have memory banks and they continually feed the body cells with instructions about the formation and functioning of body organs. This way co-ordination among the billions of body cells is achieved.
ЁЯФ╢ DNA is found in every living organism except in human RBC and certain types of viruses. An adult human body has 600 billion “energy packets” of DNA. In shape and chemical composition, all of these are similar whether in humans or animals or even in grass blades. The key to all of life’s diversity is hidden in DNA. The particular order of its constituent bases determines whether an organism is a human or a bird, fish, insect or vegetable. An Indian-American scientist Dr. Hargovind Khurana made path-breaking discoveries about the structure of RNA (ribonucleic acid) and was awarded the Nobel Prize in 1968.
