Using a previously developed method, Singer and co-workers have now labeled RNA transcripts and quantitatively measured the synthesis of RNA in living cells. They find that only a small fraction of the RNA polymerases that bind the promoter actually produce messenger RNA. They also observed much faster elongation than previously reported, along with frequent long pauses.
