 What's a gene? So that's a great question. I think the traditional view of a gene was a stretch of DNA that contained both a promoter, right adjacent to the start of transcription, and then a series of exons that were pieced together to create a transcript, which creates a protein, which then has some function in the body. And I think we had, you know, when we talked about genes in the genome, we often talk about it's just one to two percent of the genome that contains coding regions, these pieces of these exons that are parts of genes. And the rest of the genome was really not that important. Well, I think our view today is dramatically different, and we now recognize that there's a lot more control of that gene that is influenced by not just the promoter region right upstream of that gene, but in fact elements all over the genome that can come from far away and act in control of a gene and its expression and its function.
