Katie looked up, eyebrows raised. "There's a lot of problems with your idea, hun," she answered, quickly recalling her basic biology class from before she joined the Society. "Most importantly, animal cells and plant cells have different structures to them. In addition, there's a lot of difference between, say, a human and a sheep. I wouldn't know where to start on either of them." She paused briefly, thinking over any further problems altering a human's genetic makeup could produce.
"I don't think I would want to experiment on people or animals, even if I could," she said. "What if I turned a test subject into a mutated monstrosity, and didn't know how to turn it back? Plants are easier to work with because their bodies are much easier to manipulate. If I was to alter myself, I'd have to keep track of all my internal organs, the way they're shaped, how they function... I don't think I could change anything without liquefying my own organs. I haven't seen the insides of a human to study and work with." She shuddered at the thought.
