00:13

We're talking biology with Dr. Ruth Tennen, and we're going to talk now about biotechnology.

00:21

This is kind of flowing in the line of thought here. What is in vitro mutagenesis?

00:28

So, in vitro means "in a test tube." And mutagenesis means "making mutations."

00:34

So it's a way of making mutations outside of a cell.

00:37

And so you could imagine, you notice that people who have a certain type of cancer have a certain mutation and you want to study that in cells...

00:42

So you would take the DNA, mutate it in a test tube, put it back into a cell, and then kind of study the function.

00:51

At a banal level, we had "test tube babies," where we combined sperm and an egg in a test tube, and then put it back in a woman's womb...

01:01

And IPO happened nine months later...so is that...?

01:06

So that -- the in vitro part is the same. In that case, you're not really mutagenizing anything...

01:12

But you could imagine that if your embryo had some genetic defect...you would be able to do that -- you could wash it essentially...
