So therefore, if we were to do this, what we'd need to do is sequence that region in all these different mammals and ascertain if it's the same or if it's different. So if it is the same, this indicates that that site is important for a function, so a disease mutation should fall within that site.
所以如果我们真的要这么做， 我们需要做的是测出所有不同哺乳动物那一区域的序列， 确定它们相同 还是不同。如果序列相同， 表明这个地方对某一功能很重要， 疾病突变应该是发生在这个位点。
