由此猜测，这三区具有维持稳定结构的功能。A305S， V308A， A310S， G316A与H319A仍保有活性但降低了偶合效率，且位在螺旋环柱的同一面，暗示这些胺基酸可能与质子运送有关。

Double helix model significance, not only means that has verified the DNA member structure, it also has prompted more importantly the DNA duplication mechanism: As a result of the gland fat ling always with the thymine pair, the bird fat ling always with the cytosine pair, this explained that two chain's basic group orders are each other supplementary, so long as had determined a chain's basic group order, another chain's basic group order also determined.

双螺旋模型的意义，不仅意味着探明了DNA分子的结构，更重要的是它还提示了DNA的复制机制：由于腺膘呤总是与胸腺嘧啶配对、鸟膘呤总是与胞嘧啶配对，这说明两条链的碱基顺序是彼此互补的，只要确定了其中一条链的碱基顺序，另一条链的碱基顺序也就确定了。
