I have a genetics phd and work as a bioinformatician. It takes time for concepts to fully "sink in" in biology. Learning one independent theory/fact/concept is great, but it is when you hook it up to all your other knowledge that it becomes powerful. I would read as much as you can, wait a month, then go back and re-read it. I promise you'll see and think about things you haven't before. The utility, in my opinion, of a phd is that you had 4+ years where you were immersed in this environment and hopefully everything sunk in. Biology is also not as black and white, cause and effect, strictly mechanistic as CS/engineering. Always think about exceptions and grey areas.
