Don't. No School is going to care that you went to UCB vs UCSB/UC Davis etc. Your GPA is excellent just focus on getting a good GRE score and you will be fine for grad school apps. You are already working in a lab getting research experience which is the most important piece of your application for graduate school. You can always get an RA/Lab tech position at one of these schools after you graduate.
I transferred from one UC to another. Even though they were both on the quarter system I had to repeat quite a few classes since there was no transfer agreement in place. I had to repeat GE's again. Its not worth the hassle and extra money... trust me. Unless you already have the transfer agreements with your respective department at UCB don't risk it.
