This is the first installment in a series dealing with events leading up to the stable elongation complex of RNA polymerase, DNA and the growing nascent trancript. After things get going, I will begin assembling and cross-referencing the posts, providing an order for those who want to step in at their level of understanding. The levels will range from beginner to specialized researcher. I will include very basic descriptions primarily to establish a baseline of my assumptions. Introductory essays will usually appear after I have gotten a section going because it is far easier and better to write an introduction after you know exactly what you are introducing.
