Beyond the basics, you should be fine. By basic, I mean RNA, DNA, etc. You certianly do not need to know something like what technique PAGE is or every protein in some far flung complex. It really is an application exam that tests assesment of information with a background in the subjects, much like a doctor is not a human encyclopedia, though there are some free rider questions that test pure recall as example #2 shows. (much like a doctor is a human encyclopedia, hehe.)
