You, like other living systems, are an amazing energy transformer.

As you move your eyes to read these words, your body is busily converting chemical energy from your lunch into kinetic energy and thermal energy (heat). Some of them are eukaryotic (human), but many more of them are prokaryotic, thanks to the friendly bacteria of your gut, skin, and other body systems.

Learn why traits run in families and how they're passed on.

We'll look at Mendel's model of inheritance, see how it's been revised and extended in the past 150 years, and get a sneak preview of the modern concept of a gene. This seemingly simple polymer, made up of just four different types of monomers, serves as the genetic material for all living organisms.
