Hey,
As long as you don't have too many unfineshed pre-reqs, you should be fine. Especially if those pre-reqs are non-science ones. When I applied to UCB, I still had not taken anatomy, my second biology course, and animal phsyiology lab.
I took the anatomy course at a CC because it wasn't offered with lab at my school. I could have taken it at Berkeley, but I wanted to actually enjoy my summer!
