Tn other words、 an adenine forms one member of a pair on either chain, then on these assumptions the other member must be thymine : eimilarly for guanine and ytosine. The sequence of bases on a single chain does not appear to be restricted in any way. However, only specific pairs of bases can be formed, it follows that 計 the Sequence of bases on one chain is given, then the sequence on the other chain js automatically determined. Tt 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.
