1)In other words,if an adenine forms one member of a pair,on either chain,then on these assumptions the member must be thymine;similarly for guanine and cytosine.The sequences of bases on a single chain dose not appear to be restricted in any way.However,if only specific pairs of bases can be formed,it follows that if the sequence on the other chain is autmatically determined.
2)It has been found experimentally that the ratio of the amounts of adenine to thymine,and the ratio of guanine to cytosine,are always very close to unity for deoxyribose nucleic acid.
3)It is probably impossible to build this structure with a ribose sugar in plase of the deoxyribose,as the extra oxygen atom would make too close a vander Waals contact.
