Classes of behaviors may be controlled by separate initiators.
The first of these explanations implies that pure carcinogenic initiators may form a separate class of genotoxic agents from complete carcinogens, and perhaps of greater interest, that 4N might provide a valuable model compound for the study of carcinogenic promotion in the rodent liver.
Given that the initiator consensus is the initial binding site for RNA polymerase II, it is not far-fetched to speculate that small differences in the sequence may play a role in determining either the affinity of polymerase II or the energy required to separate the DNA strands and initiate transcription; both of which could potentially modulate the quantity of transcript produced.
A measure of who was the initiator of play was gained from separate analyses of pouncing which begins with one animal.
This proposed method involves making two separate but nearly identical HIPEs: the first with an oxidizing initiator and the second with a reducing agent.
Individual motifs that separate energy from translation promoters include a degenerate pyrimidine-rich initiator element enriched near the transcription start site in translation genes (YYCTTTYY), and a GC-rich sequence found to be enriched only in energy generation genes (GCGGA).
For the formation of noncross-linked and cross-linked PNIPAAm shells on Au NWs, the above Au NWs at initiator solution (8 mL) was equally divided into two separate round-bottomed flasks (labelled with I and II).
Transcription initiation at these two sites appears to occur by two separate mechanisms, with the upstream start site being specified by and dependent upon an initiator-like element, whereas the downstream sites require the presence of the TATA box.
The incidence of abdominal or pelvic surgeries during the follow-up of the tegaserod initiator or comparator cohorts was analyzed using proportional hazards regression, with separate models developed for abdominal and pelvic surgeries and for gallbladder surgeries.
Aqueous solution containing a monomer, cross-linker, and the initiator was injected into a cell consisting of a pair of glass plates separated by a silicone rubber.
