They had pieced together pieces of a scientific puzzle that scientists had been working on for many years. With the discovery of this model a new way of understanding life began -- humans could understand the basic building blocks of life for the first time in history. 2 Image Source 3 DNA is a double-stranded molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. 4 3,000,000 species share this genetic code. The DNA alphabet consists of four letters that represent the four chemical bases that make up the rungs of the DNA – A, T, G & C . ● A - adenine ● G - guanine ● C - cytosine ● T - thymine Be sure to note that rungs are made of combinations of “ A and T ” or “ C and G .” The h...
