Transcription associated with a terminal deoxynucleotide transferase gene initiator element is shown to respond to the transcription factor GAL4-VP16 both in vivo and in vitro. High-level transcription requires both an intact initiator element and bound activator. Transcription from this initiator-directed promoter is synergistic in vivo in that five GAL4 DNA binding sites yield 36 times the ex...

styrene polymerization through frp and atrp methods was carried out at 110oc, while in-depth studies were performed by monte carlo simulation.the changes in monomer conversion, initiator concentration, average molecular weight, and polydispersity index were computed over the course of the polymerization. as the results indicate, compared to atrp, the frp reaches higher conversion in a similar r...

electrochemical aptamer-based sensors attract a lot of interest as useful methods because of their low cost, accuracy, sensitivity, and simplicity. an electro-active redox molecule comprises the main part of the electrochemical-based sensors. ferrocene is one of the most popular redox molecule used in biosensor fabrication. but, instability of ferrocenium ion in strong nucleophilic reagents and...

The cyclic voltammetry of both bulk manganese sulfate (BMS) and nano manganese sulfate (NMS) were studied using 0.1M KCl supporting electrolyte and glassy carbon working electrode. The redox behavior for both bulk (BMS) and MnSO4 (NMS) sulfate was studied voltammetrically in presence and absence of Doxorubicin (DR) using three electrodes system, silver- silver chloride (Ag/AgCl), pla...

Mixed-initiative in dialogue does not mean that either speaker is free to take the lead in the conversation at any time. Rather, who can show initiative, and when, is restricted. In this paper, we define initiative and control as two levels of dialogue phenomena, and give further evidence for our theory of restricted initiative that control belongs to the initiator of a discourse segment. We sh...

This article reviews various initiator used to synthesize high molecular weight (MW >10,000 g/mol) of polylactic acid (PLA) through ring-opening polymerisation (ROP) lactide. ROP has been chosen as the best method in producing PLA. On other hand, stannous octoate (Sn(Oct)2) reported catalyst for method. Many researchers have studied that rate with presence only Sn(Oct)2 is slow compared lact...

We have sequenced a methionine tRNA from mosquito mitochondria, and examined its structure using nucleases S1 and T1 under non-denaturing conditions. The sequence is highly homologous to a putative initiator methionine tRNA gene from Drosophila mitochondria. Its anticodon stem contains a run of three G-C base pairs that is characteristic of conventional initiator tRNAs; however, nuclease S1 ana...

Electrode potential of 2-(2,3-dihydroxy phenyl)-1,3-dithiane (DPD) was investigated by means of cyclic voltammetry (CV) at various potential scan rates. The calculated value was compared with the experimental value obtained by cyclic voltammetry (CV). All experiments were done in aqueous phosphate buffer solutions at different pHs. The experimental redox potential of DPD was obtained to be 0.75...

A dencentralized consensus protocol refers to a process for all nodes in a distributed system to collect the information/status from every other node and reach a consensus among them. Two classes of decentralized consensus protocols have been studied before: the one without an initiator and the one with an initiator. While the one without an initiator has been well studied in the literature, it...
