The expansion of American citizens was huge and outstanding. They wanted more and more from a new land, and, indeed, they knew how to achieve it. In search of new settling they traveled from place to place, all way long till they found a perfect spot. They checked new, not discovered lands and made a decision to stay or to go on and on. The countryside and surroundings were breathtaking and not habitable, so pleasant to the eye, One couldn’t help himself and stayed. Some spots on the other hand were particularly difficult to habit due to the weather conditions, soil which was difficult to grow plants on, hostile and harsh background. Nonetheless the urge to see, explore, and know more was irresistible. In 1800 the western boundary of the United States was immerse and spread to Mississippi River , the land was affluent and rich with natural resources.  This year is quite remarkable, Louisiana belonged to France , Napoleon whose position was unquestionable was about to be...

The following article will focus on PCR – its unquestionable role in modern medicine; its prime role in crime scene investigation where everything One needs are pieces of evidence deeply rooted in the background of hard science – the science which is not easily put under question or doubt. Reverse transcription of polyadenylated RNA (the vast majority of cellular mRNA) with the subsequent amplification of the copied DNA via the polymerase chain reaction is an important technique in assaying so-called “fusion” transcripts. Fusion transcripts occur in rare instances in which chromosomal translocation fuses transcribed regions of two genes. These may result in fusion proteins in which coding information from one gene is fused to the coding information of another gene, producing a hybrid protein. These proteins may retain functionality, as in the case of the bcr/abl fusion protein, but the regulation of these proteins’ functions may be abnormal. Chronic myelogenous leukemia (CML) is typifi...

Blood has always been an inevitable and crucial physical evidence. It made forensic science a revolutionary field of study. Furthermore it is omnipresent in all violent crimes. Blood is a vector which indicates the sequence of events in a crime and match the suspect to the crime scene. The DNA typing has got a significant impact on violent criminal investigations. What is blood? It  is a   body fluid   in humans and other animals. It is composed of   blood cells   suspended in   blood plasma which constitutes 55% of blood fluid, mostly water (92% by volume), it delivers necessary substances such as   nutrients   and   oxygen   to the   cells   and transports   metabolic waste   products away from those same cells. and contains dissipated   proteins,   glucose, mineral   ions,   hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. ...
