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。

Hydrolysis of the mischarged amino acids in theediting reaction will rely on the proper binding and correct recognition of both mainchain and side chain of the substrate. In general, the editing active site ofLeuRS-ED has a very rigid structure with a defined stereochemistry and usesa number of conserved residues to precisely bind and recognize the misactivatedamino acids and discriminate and reject the cognate amino acid, specifically usingMet336, Asp345, and possibly Thr247 for main-chain recognition and Thr252,Met336, and Val338 for side-chain recognition.

在编校反应中错配的氨基酸的水解依赖于对底物主链和支链的适当的结合和正确的识别。ecLeuRS-ED的编校活性位点有一个非常刚性的有很精确设计的立体化学性质的结构，采用一系列保守氨基酸残基来精确结合和识别错配的非共轭氨基酸而区分排斥正确的共轭氨基酸，具体就是采用Met336、Asp345，另外可能还有Thr247对底物主链进行识别，采用Thr252、Met336和Val338对支链进行识别。
