All you have to do is mutate the DNA, which is very straightforward to do in molecular biology, and now you can tag absolutely any protein that you're interested in.

你所需要做的就是使DNA变异，这在分子生物学力是很容易做到的，你可以用它标记,任何你感兴趣的蛋白质。

You can also assign to a list, or to an element of a list. So ivy sub 1, f -15 or example, could be assigned minus 15, and that will actually mutate the list.

此外你还可以给一个数组，或者数组内部的元素赋值,比如ivy。sub，可以被赋值为，这确实改变了数组。

Instead I'm going to be expecting the address of some int and the address of another int and thanks to this address I can literally find this address in RAM, do anything I want there, -- return and what I've just done is actually changed or mutate the values of those original variables.

我们所期望的是int型地址,和另外一个int型地址,幸亏这个地址，我可以找在RAM中找到它的地址，然后做我想做的事情，返回我处理后的东西,我可能改变了这些源变量。

"They don't mutate,and the reason they don't mutate is that if they try to, the virus can't survive if you have mutations in these sites."
