these molecules are important and what they do, so that you can better understand your body and the world around you. That is a really cool thing to learn about! It can also be super useful. Once we understand how stuff works, we can start to understand how we might be able to hijack it for useful purposes, like medicine or improving agriculture. This is just the beginning. While you may not see the immediate usefulness just yet, the foundations of knowledge that you learn here will help you understand much more complicated processes and, eventually, allow you to use science for good.
