History of Genetic Engineering
Summary: Genetic engineering is performed by re-writing the code in the DNA of a molecule, placing it inside of a cell and allowing the DNA to duplicate and morph. Understand the details of how genetic engineering happens with information from a biochemistry professor in this free video on genetic engineering.
"On a molecular level, the basics of how genetic engineering works is every cell has a DNA inside of it. The cell reads the DNA and it creates whatever the DNA says. So, if the DNA says, make this molecule, the cell will make that molecule. So, what we as researchers do is we would type in what, what we want inserted into the DNA then that would get placed within the DNA by enzymes and things like what which you can buy and afterwards, that DNA is placed inside of the cell, bacteria or, you know, other types of cells. And from that point on, it's a part of the DNA. So, every time the cell replicates or is even around it should read passed the DNA and create exactly what we wrote. Now, to do it on the industrial skill, it's pretty much the same thing except now they have tanks full of the enzymes instead of little bottles of the enzymes, and they have tanks of bacteria growing or whatever cell growing instead of little bits of cells growing. The biggest thing issue comes into purification 'cos anytime genetically modified creature is what it reads the DNA, it's not going to do just create what you wrote. It's going to be create everything else that's written on that piece of DNA, too. So, the real trick comes into after getting a super stuff from your genetically engineered creature. How do you pick out the one thing that you want? Or, how do you keep out the things that you don't want? And this really becomes a problem, say, if you're using a cow as your genetic factory, or genetic work course, you know, and you want whatever item you make to come out through its milk. You know, you definitely don't want contamination here or anything like that. So, it's essentially I would say a 3-step process where the people, the researchers, decide what to write or which molecule to create. Getting that on a piece of DNA and getting that piece of DNA into some sort of a cell and having that cell replicated and that's I would say is the 3-step process of how genetic engineering is done."
