restriction sites (Wiki 2008). This restriction mechanism has become useful in helping scientist to identify where restriction sites are located on a strand of DNA. This knowledge is also helpful in analyzing and mapping genetic structures as well as in molecular cloning (Biotech 2008). Agarose gel electrophoresis is an effective way of sizing the DNA to determine the number of base pairs. The microscopic pores inside of the gel allow molecules to travel through them according to their size and shape

extraction‚ or binding of the DNA to a solid phase support (either anion-exchange or silica technology). DNA is usually recovered by precipitation using ethanol or isopropanol. The choice of a method depends on many factors.The required quantity and molecular weight of the DNA‚ the purity required for downstream applications‚ and the time and expense.The separation of DNA from cellular components can be divided into four stages. Disruption‚ Lysis‚ Removal of proteins and contaminants and Recovery of

this area that make the evolution and progression of man as a race to advance at a rapid rate has made me develop a strong wish to learn more about the concepts of life‚ the processes and factors that lead to certain changes in our bodies at a molecular level. This led me into wanting a degree in biomedical science which studies the basic biological systems that establish all life from a cellular‚ tissue‚ organ and whole body perspective. The specific area of biomedical sciences that intrigues

Diffusion is a natural act that takes place in the human body in order to utilize and absorb important concentrations into the body. In order to understand how diffusion works‚ it is important to understand how temperature plays a role. In connection with diffusion‚ a certain temperature must be obtained to begin the process. Introduction Diffusion is very important in the body for the movement of substances. An example would be the movement of oxygen from the air into the blood and carbon dioxide

York State back in the summer of 2001. There had been a series of tests that had been administered to Michael due to a benign tumor that was found in his brain after he suffered a fall that caused a head injury. Michael Colombini underwent a routine imaging procedure that was performed at Westchester Medical Center; where earlier in the week Michael underwent brain surgery to remove the benign tumor that was found in his brain. The scheduled MRI was considered a routine post-operative procedure to find
