 Hi, guys. So today we're going to talk about the actual function of DNA, and I'm going to make some notes for you just so you understand. DNA provides the information to build protein. And protein is what makes you you. You look the way you do because of proteins. You function the way you do because of proteins. And DNA contains the information necessary to build all of those necessary proteins. There's two stages of this process, and we're going to deal with them separately. The first stage of DNA to protein is called transcription. Hmm, transcription. And the second stage is translation. And today's lecture is on transcription, and the next lecture we're going to do is on translation. It's kind of nice. Transcription is very similar to DNA replication, so hopefully that will keep you a little bit not quite so overwhelmed by the molecular details. So let's look at an overview before we start.
