What is the main topic of this episode?
Welcome to Skeptical Sunday. I'm your host, Jordan Harbinger. Today I'm here with Skeptical Sunday co-host Michael Regilio. On the Jordan Harbinger Show, we decode the stories, secrets, and skills of the world's most fascinating people and turn their wisdom into practical advice that you can use to impact your own life and those around you. Our mission is to help you become a better informed, more critical thinker. And during the week, we have long-form conversations with a variety of amazing folks from spies to CEOs, athletes, authors, thinkers, and performers. On Sundays, though, we do Skeptical Sunday, where a rotating guest co-host and I break down a topic you may have never thought about and debunk common misconceptions about that topic. Topics such as fast fashion, weddings, the death industry, homeopathy, hypnosis, diet pills, and more.
And if you're new to the show or you want to tell your friends about the show, I suggest our episode starter packs. These are collections of our favorite episodes on persuasion, negotiation, disinformation, psychology, cyber warfare, crime and cults, and more. That'll help new listeners get a taste of everything we do here on the show, or almost everything. Just visit jordanharbinger.com slash start, or search for us in your Spotify app to get started. Today, DNA and genes are everywhere, both figuratively and literally. Get your mind out of the gutter, folks. Not only are they the building blocks of every living thing, but they also hold the secrets to our ancestry, unlock the mysteries of unsolved crimes, and help doctors predict and treat potential health conditions. Even Maury Povich famously used DNA to determine if somebody is or is not the father.
You are not the father.
But as technology advances, we're now capable of manipulating DNA, raising profound questions about what it means to be human. Are we on the brink of a beautiful new age or stepping into a dystopian sci-fi nightmare? To help us navigate this microscopic landscape, skeptic Michael Rogelio is here to help us unravel the double helix of ethical dilemmas and excitement around DNA. Hey, Jordan.
If I may lay a quick compliment on you, you seem quite healthy and smart. Thank you. I do what I can. Sure, it's important to stay fit and sharp, but the fact of the matter is you had little to do with being healthy and smart. In fact, you had no say in the matter at all. You were predetermined to be those things. You just made the most of it. So you're talking about my genetic predisposition, right?
Yep. It's in your genes and it's in your DNA. So I think we all have some sense of what our DNA and genes are, but why don't you break it down for us? I don't actually know the difference.
Okay, sure. DNA, or deoxyribonucleic acid, is a molecule, and a molecule is a bunch of atoms stuck together. This particular molecule, DNA, is coiled up in the nucleus of every cell in our body, and each coiled-up strand of DNA is the complete blueprint to make, uh...
You. Yes, I've seen Jurassic Park. But I'm still mind-blown by all this. Cells are really small, and the idea that a cell can replicate itself is pretty wild. But the fact that each cell also holds the blueprint to make another entire me is just crazy. Yeah.
Cells are really small, and to illustrate this, let me hit you with this fact. Every time you scratch your nose or rub your arm, dead skin cells fall off your body. Humans shed about 600,000 skin cells per day.
You'd think you'd notice if you lost 600,000 of pretty much anything, but no, I've never noticed this, generally.
So, we're talking tiny here, and the DNA strand in each cell isn't just coiled up in the cell, it's actually coiled up in a much smaller part of the cell, the nucleus.
Aha. Okay, so 7th grade science class coming in handy here. DNA is obviously extra tiny if it's all curled up in the nucleus of the cell. Uh, actually, only kinda. Kinda sounds a little bit less scientific than we like to be on Skeptical Sunday, but I'm gonna roll with it. Okay, look.
