In bacteria, the rho factor can terminate this process, and sigma factors help initiate it.
 
The FACT complex assists in one phase of this process, and one protein that initiates this process is
 mutated in Spinocerebellar Ataxia 17, in which its poly-Q tract is expanded. This process is inhibited by
 actinomycin D. In bacteria, the rho factor can terminate this process, and sigma factors help initiate it.
 Roger Kornberg isolated the protein complex responsible for initiating this process, which assembles itself
 at the TATA box. RNA polymerase II binding starts this process, which creates its product from 5 prime to
 3 prime. For 10 points, name this genetic process in which DNA is read and written to RNA.
