By doing so, they virtually guaranteed they would make a virus that could pass betweenmammals.
这样,使得他们实际上能够制造出测定哺乳动物间传播的禽流感病毒。
And so it proved.
最终,这也得到了证实。
When they tested it on ferrets, it passed through the air from one animal to another.
当他们在雪貂身上进行测试后,病毒经过空气从一只传到另一只。
Moreover, closer inspection showed that two other mutations, N158D and T318I, hadspontaneously got tangled up in the mix.
此外,进一步检测显示,另外两种变种,即N158D和T318I,同时也紧紧纠缠于病毒中。
What all this means, then, is slightly obscure.
实验的结果看起来有点晦涩。
Dr Kawaoka s purpose was to study how the mammalian-transmission mutations worked.
河冈博士的目的是研究哺乳动物间传播的变种如何起作用。
In this, he succeeded.
在这一点上他成功了。
He found that N224K, Q226L and N158D all control areas in the head of the HA proteinie,the hookand probably help it attach to the mammalian flavour of sialic acid.
他发现了N224K、Q226L和N158D位于HA蛋白头部的控制区,它们有可能帮助HA偏好于哺乳动物的唾液酸。
