Work Step by Step
Think of a scaffolding protein as being like a pencil case. You could put a pencil, a pen, and a highlighter in the case and be ready to read, annotate, and highlight your book. You could use a larger pencil case to hold a knife, a block of survival food, and a pen in there and be ready to survive a small crisis and write down what happened. These cases are tools to hold other tools, but the exact types of tools you have will determine what you can process.
