DNA molecule. Illustration of a segment of the molecule deoxyribonucleic acid (DNA). This is the more common beta form of DNA in that the spiral winds clockwise when viewed from above. DNA contains all the inherited instructions needed to produce a living organism. The DNA molecule is made of two strands of atoms twisted into a helix. Each strand comprises an outer sugar-phosphate backbone (green),from which nucleotide bases project. Paired bases (red/orange & blue/purple) form the genetic code | |
