"Science" is a very broad field.

In some sense, protein folding is a chemistry problem, in that it is entirely about determining the structure of (a very specific type of) molecules.

In another sense, protein folding is a computational problem that is a necessary input to answering higher level questions in the field of biology.

Put another way, this allows researchers in biology to not need to care about the science of protein folding.
