Bonding Bases

 

Bonding Bases

Watson discovered the double helical structure of DNA while looking at possible ways that two strands could fit together. If the sugar-phosphate backbone were on the outside of the molecule, the bases adenine, cytosine, guanine and thymine would have to bond to each other in some way.

Try to get two of the bases to bond together. If you need a hint, check back to the sections on Hydrogen Bonding and Chargaff's Rules.

Did you find both pairs? If you've only found one, try and find the other.
