Why Do Scientists Use Genetic Engineering?

Video Transcript

"Scientists use genetic engineering like a carpenter uses a hammer. For a scientist who's studying the life sciences, it's simply a tool which we could use to learn more or get, you know, our organisms, our creatures to do what we want them to do. Simple example would be, if I want to start to study a particular molecule that's made in the human body, say, one of our hormones or something like that. I would find the code for that hormone, I would program it, I would genetically engineer it into a bacteria or some cells and have it make millions of copies of that molecule, and then I would use, you know, different tools to study the molecule. It's a factory for us to create any sort of life molecule that we need. Many thing from, you know, blood cells to any sort of protein in your body to any sort of enzymes, we can create with genetic engineering."
