Human DNA. Computer molecular graphic of human Deoxyribonucleic Acid (DNA). DNA determines a person's hereditary characteristics. This is the more common beta form of DNA,with its two strands winding clockwise around each other when viewed from above to give a helix shape. The atoms are colour-coded: phosphorus is yellow,oxygen is red,carbon is dark blue & nitrogen is light blue; hydrogen is white when it occurs singly,but green when two or more are attached to the same atom. The 2 strands are made of sugar-phosphate groups. They are connected by nitrogen-containing nucleotides. The exact sequence of nucleotides determines the genetic code | |
