Short Stuff: Genetic Mutations

All right. Well, let's get into this. Let's talk about DNA or deoxyribonucleic acid, as we all like to call it. Such a great word. Around the campfire. That's a molecule that's going to carry genetic material, almost a mutation, when you're developing as a future human.

And structurally, I think we've all seen the โ€“ if you've seen Jurassic Park, you've seen what these double โ€“ this double helix looks like. It's a long โ€“ molecule comprised of nucleotides. And there's two strands to that coil that form the double helix that kind of wind around each other. And that's what the DNA, the full DNA, what would you call it? Just molecule looks like?

Short Stuff: Genetic Mutations

Yeah. And, you know, like you mentioned, as these cells divide and the DNA is making copies of itself, there might be errors here and there. And that's where those mutations come from. And if they're in the egg and sperm cells, those are going to be passed on to the next generation. So that's a genetic mutation that's going to carry on and cause disease or genetic disorders.

You can also have what's called a somatic mutation, and that only affects you. It's not inherited by your future kids.

Stuff You Should Know
Short Stuff: Genetic Mutations

Yeah, and our cells are constantly copying themselves, either replacing old cells or damaged cells. And when that happens, when they're doing that copy, that double-stranded DNA is going to split into the two parts, and each strand is copied on its own, and then they come back together. And when that happens, there can be errors.

Short Stuff: Genetic Mutations

The good news is it's approximately one in every 100 million replications this happens. So that's a pretty good statistic to have in your hip pocket. The other good news is DNA knows what it's doing. So it generally knows when an error happens, and they try to and often can repair and correct that before any problems arise.
