DNA molecule. Computer graphic representing a segment of the molecule Deoxyribonucleic Acid (DNA). The alpha (at left,anti-clockwise spiral) form & beta (clockwise) form of this molecule are seen. DNA contains all the inherited instructions necessary to produce a living organism. Atoms are depicted as colour-coded spheres: phosphorus (green),oxygen (yellow),carbon (orange). The DNA molecule is composed of two strands of atoms twisted into a helical shape. Each strand consists of an outer sugar-phosphate backbone,from which nucleotide bases project (mauve). The bases are paired in a complementary fashion,making up the DNA genetic code. Beta DNA is a more common form | |
