DNA molecule. Computer representation of a segment of the molecule Deoxyribonucleic Acid (DNA). This structure contains all the inherited instructions necessary for the development of most life. Here colour-coded spheres depict atoms: red (oxygen),yellow (phosphorus),blue (nitrogen),white (carbon). DNA is composed of two strands twisted into a helical shape,each strand consisting of an outer sugar-phosphate backbone (red,yellow). Projecting inward from this backbone are bases (blue,white) that pair in a complementary fashion to form a code of instructions. Many base pairs are represented here. The code in genes is formed by this arrangement of base pairs along DNA | |
