  DNA. We talk about it so much---it is the ultimate director for cells and it codes for your traits. With a molecule that has a function like that, it makes sense that when you make another cell---like in cell division---you would also need to get more DNA into the new daughter cell. And that introduces our topic of DNA replication, which means, making more DNA. First, let’s talk about where and when. First where---well if it’s in a eukaryotic cell, it occurs in the nucleus. However, remember, not all cells have a nucleus. Such as prokaryotic cells. They don’t have a nucleus. Still both prokaryotic and eukaryotic cells do DNA replicationm but there’s some differences between the two that this clip doesn’t go into. Next, when. When does this happen? Well a cell is going to need to do this before it divides so that the new daughter cell can also get a copy of DNA. To get specific, in a eukaryotic cell, that’s going to be before mitosis or meiosis in a time known a...
