Telomerase is a unique reverse transcriptase in that it repetitively uses a short piece of its RNA component as template to synthesize DNA. A new crystal structure of a part of the Tetrahymena telomerase ribonucleoprotein reveals how reverse transcription is limited to this specific template region.
