Deoxyribonucleic acid, popularly known as D.N.A is the building block of life. Every organism, except for a few viruses, have D.N.A as their genetic material. It is responsible for transmitting vital characters from one generation to another. But, these are all basic facts known to practically everyone.
The curious fact is that, a few elements is the basic block of life. These complex molecules are responsible for all our characters and helps pass them from one generation to another. Somewhere in the past, due to reasons yet not fully understood completely, the first prototypes of nucleic acids were created. These then combined with each other and became more complex and evolved into life.
