格莱文博士最后还开玩笑地说，其它星系的生命体由于不同的起源条件可能是基于右型氨基酸所构建起来的也说不一定。
Life in other star systems with different early conditions could have built up around right-handed amino acids, said Dr Glavin.
从另一方面看，如果这种对氨基酸的优先选择机制早在生命起源之前就已经存在，那就说明在生命出现以前，必定存在一种比生化反应还要早的化学反应过程。
On the other hand, if there is a mechanism to choose handedness before life emerges, it is one less problem prebiotic chemistry has to solve before making life.
该基因编码一个含有211个氨基酸的多肽，属于水稻WRKY基因家族中可能起源于单子叶植物和双子叶植物分化后的一个亚家族。
This gene encodes a polypeptide of 211 amino-acid residues and belongs to a subgroup of the rice WRKY gene family that probably originated after the divergence of monocot and dicot plants.
