How do eukaryotic cells, such as the cells found in our body, actually regulate gene expression? Well, because eukaryotic cells are so much more complex than prokaryotic cells, we see that the method by which gene genes are regulated in eukaryotic organisms is much more complex than that in prokaryotic organisms. And there are many different levels at which gene regulation and gene expression can actually take place. And in this lecture, we're going to focus on the most common method of regulating genes in eukaryotic cells, and this is on the level of transcription itself, so by actually changing the rate at which transcription takes place. So in this lecture, we're going to briefly discuss the different components that are found along a eukaryotic gene. So this basically describes a diagram of a basic eukaryotic gene.
