This report recommends that no bonuses be awarded to the production department. Responsibility accounting assigns costs, revenues, and profits to those managers who have direct responsibility (Hansen, Mowen, & Guan, 2009). Responsibility accounting forms the basis of assigning responsibility, establishing performance measurements, evaluating performance, and awarding rewards. The production manager is responsible for the costs incurred in the production department. The standard cost and quantities establish the performance measurements. The production manager performance can be evaluated against the standard costs and the variances computed. The variance analysis forms the basis of awarding the bonuses. The variance analysis shows that the ...

Transcriptional regulation of gene expression

Gene expression in eukaryotic cells is regulated at transcriptional, post transcriptional and translational levels (Tomizawa,  Lekstrom-Himes, and Xanthopoulos 17). Transcriptional control is the primary means of regulating gene expression. Eukaryotic transcriptional control functions at three levels: modulation of the activities of activators and repressors; variations in chromatin structure; and effect of activators and repressors on assembly of initiation complexes (Lodish et al. 368). Regulation of transcription initiation is the most widespread form of gene control in eukaryotes. However, in some cases, transcription may be attenuated and regulated at subsequent steps, such as during or after the transcription process (Cooper ...

It is hard to imagine a modern life without polymers. They are literally everywhere. What makes them so useful and unique? Chemists look inside the structure of a matter in order to explain specific chemical or physical properties. Polymers do have unusual structures. Their large molecules consist of particular segments that are repeated by some pattern. The segments are called monomers. As a result of polymerization, monomers completely change their properties. For example, polyethylene (-CH2-CH2-)n, “the largest tonnage plastic material”, is a waxy solid polymer (Nicholson 6). However, ethylene by itself is a gaseous matter. Even though man-made polymers were introduced relatively ...
