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 ...

Introduction

The United States is one of the most developed countries, but it is also one of the countries with the highest level of income inequality. According to research, more than half of the nation’s income goes to only 5% of the population, while the remaining half is shared by the 95%. One way of measuring a nation’s income inequality is through the Gini coefficient. The Gini coefficient measures income inequality on a scale of 0 to 1 wherein 0 corresponds to total equality; a scenario wherein everyone is earning the same amount while 1 corresponds to total ...

Criminal activities among the youth and women are high in areas with low incomes like slums and poverty-stricken populations. A Rage in Harlem (1957), by Chester and ‘’The Corner’ by Simon and Burns focus on the criminal activities taking place in inner cities. A Rage in Harlem focuses on sexual and violence among the youth in the City of Harlem where majority of its population is black who live in congested dwellings, feeding on each other’s throats. This shows how poverty is prevalent in among the blacks living in Harlem while the whites are living in mansions on a ...
