Searching for the relics of primitive coding system

遗传密码是储存在基因中的蛋白质蓝图的格式。格式的组合非常合理，但在生命的早期阶段可能会有所不同。在这项研究中，我们使用几种方法在蛋白质的基因组序列和氨基酸序列中寻找过去遗传密码的遗迹。因此，我们得到了一些候选文物，尽管我们还需要进一步研究才能获得确凿的证据。

The genetic code is the format of the blueprint of proteins that is stored in genes. The format is assembled very reasonably, but it may have been different in the early stage of life. In this study, we search for the relics of the past genetic code in genomic sequences and amino acid sequences of proteins using several methods. As a result, we got some candidates for the relics, although we have to study further in order to obtain conclusive evidences.
