Description:This text is just really great. The choice of words that go into the explanations are top notch. This was the requred textbook in my recombinant DNA course.It is written by biologists for biologists; very technical very exact; again just absolutely terrific for both review and in depth understanding.The only downfall I would say is that the Index isn't as good as it could be, but other than that I think every biology graduate student should own it....yeah its that good IMHO.
