Thank you, that makes a lot more sense than some sort of “gain” (as in, increasing output levels) of “function” (as in, a mathematical calculation where each input has exactly one output).

I’m thinking what the heck is a Gainof Function?

Yeah the function here is not a mathematical function - it just means functionality, like the thing that it can do. Sometimes we biologists can be spectacularly uncreative in naming things :)

Heh, It makes more sense if you think about it medically. Like, the gain or loss of function in a limb or organ.

For a virus I suppose this would be function in reproduction.
