Frankie Jonas stops by to chat with us about your best friend and mine, the humble dog! You'd think that in this, of all episodes, we'd be able to have a nice, simple definition of the topic. But guess what, no one even knows what a dog is apparently! Science!

This week, we’re joined by scientist and podcaster Amanda Wacker to talk about DNA, the building blocks of life! A blueprint for building a living thing, even!

Webster’s dictionary defines DNA as “any of various nucleic acids that are usually the molecular basis of heredity, are constructed of a double helix held together by hydrogen bonds.” I define it as the little wiggly guys inside us that make our cells and stuff. We’re both right, in our own way.

If SciShow Tangents had a smell what would it be? It’s full of knowledge, so maybe a dusty old book? We talk a lot, so maybe all of our nasty breath?  We talk about butts a lot… you know what? Podcasts don’t smell, and maybe that’s for the best.
