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 increased attention to environmental concerns and the alarming diminish of the oil reserve have commanded invention of new vehicles in our road transport system. Therefore, the oil and environmental future demands have prompted that the solution with the greatest potential is hybrid vehicles. The hybrid vehicles are those kinds of vehicles that use two or more distinct power source in making the vehicle move.

SIGNIFICANCE

The expectation that there will be a triplicating number of the global light-duty car fleet and a doubling emissions level of CO2, has prompted the significance of addressing concern on fuel efficiency in our ...

“The Game of Death” is a 1972 movie that is written, directed and produced in Hong Kong by Bruce Lee. Bruce Lee is a significant cinematic character who fundamentally changed movie scenes. “The Game of Death,” also known as Legend of Bruce Lee/ New Game of Death (1972), is not only of a dramatic reconstruction but also stands in, presumably off limits, clips from Lee’s headlining features (Teo, 1997). In 1972, Bruce Lee began preliminary filming a philosophical martial art film “The Game of Death. However, his association in the generation was upset to allow him to start ...

Introduction

Globalization and the media industry are closely related in that both connect with each other in terms of information delivery and development. Globalization plays a significant role in preserving the culture of different societies. However, this may prove difficult as media content is playing a significant role in influencing social life of the viewers. With this being part of the press, it is gaining popularity all over the world such that even countries like China that have been strict in representing their culture in addition to creating competitiveness of their media content locally and globally having to restructure their ...

Introduction

Genome imprinting is the latest technique that has genetically modified the face of infertility; it is an epigenetic phenomenon through which the parental origin of a gene is determined based on its expression. 1 There are a vast number of genes in mammals that are marked with their parental origin, and the result of this phenomenon is a single parental allele. These marked genes are known as “imprinted.” They rely on the epigenetic machinery determining their parental identity and maintaining their origin-specific gene expression. There are 100 imprinted genes estimated in human and 200 ...

Introduction

Genetically modified organisms (GMOs) are arguably beneficial socioeconomically. However, there are rising concerns over the harm GMOs pose to the humans and their environment. The process of genetic modification entails altering the genetic composition of organisms to award them properties that are more desirable. According to Rifkin (17), the world is in transition toward a biotech age as illustrated by the advancement of GMOs. In the current society, the adoption of genetically engineered crops, such as soybeans, cotton, and corn, is widespread in the United States following two decades of concerns over consumer reception, and environmental and economic impact ( ...

Cancer is the second leading cause of death in the United States. It is a term given to a series of diseases in which the cells within human body grow at an abnormal rate, thereby damaging healthy tissues . While normal cells grow and die at a specific rate according to the requirements of human body, the growth of cells is extreme when compared to the death of cells in cancerous patients. Such an abnormal growth in turn leads to tumors, which consist of a huge mass of tissues. However, in patients suffering with cancer related to the blood, there ...

Lab 1 ASA College Abstract Patau’s syndrome is a rare genetic disorder that involves trisomy 13. The condition is characterised by either an extra copy of the autosomal chromosome number 13 or a translocation to chromosome 13 from another chromosome. There are severe symptoms observed in the unborn and newborn children having this defect. Polydactyly, cleft lips, physical retardation, mental retardation, heart defects are few of the many symptoms. The disease can be diagnosed during gestation via screening methods followed by several analytical procedures like FISH, karyotyping and microarray on samples of blood and serum from the pregnant ...
