In prokaryotes it proceeds via abortive initiative cycle, while in eukaryotes immediately following this step, introns are removed from the product by splicesomes and a modified guanine cap and a poly A tail are added.  
This process is upregulated when TBP binds to the TATA box, and can be mediated by riboswitches.  In prokaryotes it proceeds via abortive initiative cycle, while in eukaryotes immediately following this step, introns are removed from the product by splicesomes and a modified guanine cap and a poly A tail are added.  This process begins when namesake factors bind to (*) promoter sites, and then RNA polymerases copy DNA into a new RNA strand.  For 10 points, name this process in DNA expression which makes up the central dogma of genetics along with translation.
