Essays on DNA Sequencing

Abstract

In the last century, the knowledge of molecular biology has increased, opening new opportunities for addressing different diseases that have been affecting all populations. Before, genome and proteomic studies were seen as complicated field due to inability to get significance understanding of disease components at the molecular level. However, with the expansion of molecular biology, different techniques and tools have been developed to aid diagnosis and treatment of diseases. In this study, these tools have been investigated to understand how the knowledge on molecular diagnosis helps in detection and treatment of diseases. This study focused on the application of ...

The rediscovery of Mendel's works on heredity in 1900 became the foundation to investigate more on genetics. However, the acceleration of the study of genetics was slow, taking more than half a century later for Watson and Crick to crack the chemical basis of heredity. In fact, their proposal, the double helical structure of DNA, became the beginning of modern biology. Over the next 30 years, the advent of recombinant DNA technology allowed us to sequence specific DNA segments (Collins & McKusick, 2001). Note that mapping specific regions of a particular DNA offers explanations to many traits, including behaviors, disorders, ...

Abstract

Actions taken at the beginning of a crime scene investigation can have far-reaching implications in the resolution of the crime, apprehension of the suspects and prosecution in the court of law. Meticulous and thorough investigation is key in ensuring that potential evidence is not destroyed or tampered with and witnesses overlooked. While many criminal investigation agencies employ a wide range of programs, techniques and equipment used in crime scene processing, the resources available and level of training vary from country to country. Apparently, the ability to investigate crimes has improved dramatically over the years with advances in information and ...
