 Let's take a look at the cell cycle. The cell cycle is the entire life cycle of a cell that includes possibly mitosis or nuclear division. If we were to throw the stages of the cell cycle onto a little circular image, what you would see is that the cell is in a stage called interface, most of the time. All of that is interface. Interface is essentially where the cell's doing its thing, hanging out, being a cell. There are specific characteristics. For example, during interface, the cell's DNA looks like this. Dude, I feel like I've got Barkley, the dog from Sesame Street hanging out here with me. So most of the time that a cell is hanging out, it's in interface. And then you'll notice that there's just this little brief period of time. There are multiple stages in this where the cell actually divides. If I were to do a visual, I would have a little cell right here with its nucleus and it's doing its thing and it's getting ready to divide and then it goes through division and the end result is two little cells like that. And maybe this one, I should have put that up here and there because it's going to go through the process again and then this daughter cell is going to go through its own little process. Whoa, did you follow what I just did? Of course you did. We're going to talk about the stages of mitosis in a second and we're going to talk specifically about the stages of interface in a second as well. But the important thing for you to recognize is that there are, like there's different stages. We could do a survey of all the cells in your body and say, okay, what stage are you in? And we can find out, are you in interface? Are you going through mitosis? Are you in a specific phase of mitosis? Are you in a specific phase of interface? There's, every cell in your body is going to be in one of these stages, whether it's getting ready to divide or not, it's going to be in one of these stages. So let's look closer at the actual process of interface and break it down into its three little parts right here.
