Base pair bonding in DNA. Molecular graphic of the guanine-cytosine base pair bond in a molecule of DNA (deoxyribonucleic acid). Atoms are depicted as spheres and colour-coded: carbon is yellow,hydrogen is white,oxygen is gold,nitrogen is silver/grey. Guanine is seen at left,linked to cytosine (foreground) by three hydrogen bonds. The DNA molecule consists of two long,helical strands held together by "rungs". Each rung consists of a pair of nucleotide bases - either guanine and cytosine or thymine and adenine. The order of bases along the rungs of the molecule information in the form of genes | |
