Computer graphics image of DNA,showing its double helix structure & associated water molecules (green). DNA (deoxyribonucleic acid) consists of two linked strands of nucleotides (blue & red),coiled into a helix. The strands are joined by the hydrogen bonding of pairs of organic bases (purple & orange) on adjacent nucleotides. The organic bases are thymine,adenine,cytosine,& guanine. The green circles show where water is likely to bind on the outside of the DNA molecule. Water serves a number of functions,& is involved in the interaction of DNA with proteins. The image shows the B form of DNA (B-DNA) | |
