In this case piling on more support will not help. Like most things that require fundamental research for progress quality trumps quantity. By support I'm assuming throwing more people at the problem.
I think it could be useful. It's true that for that kind of problem, you want to throw more money at the best people, no strings attached, and let them keep playing around until they solve it - but all other research you can get will act as a support team. The field of biology is so big and messy, that you'll likely need tons of researchers and algorithms running experiments, sorting through data and writing down the findings, so that the best of the best can have all results they need available to devise a working solutions.
That principle (from The Mythical Man Month) applies to team size. If you have multiple independent teams competing they will not have that increased overhead.
Quantity begets quality. I'd rather give 50 researchers 10 million each than give 500 million to one researcher. It's unlikely a single person is going to solve such a complex problem alone.
