Science  Many proteins that control the rate of this process contain zinc finger domains. In some organisms, the end of this process may be described as rho dependent or independent; in the latter case, the hairpin loop forms and subsequently detaches. In those organisms, a structure named for Pribnow is analogous to the TATA box, and it begins when a holoenzyme forms from the binding of a sigma factor. In eukaryotes, however, this process is followed by a step in which lariats form and introns are spliced out; in those organisms, its initiation is greatly aided by the acetylation of histones, which precedes the polymerase binding to promoters on the template strand. For 10 points, identify this process through which a DNA template is turned into messenger RNA.
