large ribosomal RNAs, mRNA precursors, and transfer and 5S RNAs.
* 1977-1979: Roeder develops cell-free systems to better study transcription. Composed of the purified RNA polymerases and components extracted from cell nuclei, the systems allow researchers to recreate transcription in a test tube in a way that faithfully mimics the real process in cells.
* 1979-1980: The development of cell-free systems leads to the identification of complex sets of proteins called accessory factors
