最近研究表明，信使RNA在蛋白质合成中，不但表现出一维序列上的对应，且在两者的空间构象上也表现出某些对应关系。

Recently, it has been proved that an mRNA molecule instructs the corresponding protein synthesizing not only in the primary structure but also in the conformation.

否则，从序列获取一个新的键值，用它作为维表中新条目的主键和事实表中的外键。

Otherwise, a new key value is taken from the sequence and used for both, a new entry in the dimension table and as a foreign key in the fact table.

这个算法也使用二维表格，一个序列沿顶部展开，一个序列沿左侧展开。

Again, you have a two-dimensional table with one sequence along the top and one along the left side. Again, you can arrive at each cell in one of three ways.
