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

Many recent imaging modalities in medicine‚ such as magnetic resonance imaging (MRI)‚ computed tomography (CT)‚ digital mammography also generate images directly in digital form. Diagnostic imaging is an invaluable tool in medicine today. These imaging modalities provide an effective means for non-invasive mapping of the anatomy of a subject. These technologies have greatly increased

DNA bender: Cren7 & Sul7 DNA benders can introduce a bend in the DNA (Luijsterburg et al.‚ 2008). Many bends in the DNA automatically provide compaction of the DNA. Two important DNA bending proteins in crenarchaea are Cren7 and Sul7 (Driessen et al.‚ 2013). They are similar in structure‚ but they have different DNA binding regions (Zhang et al.‚ 2015). Cren7 and Sul7 can be methylated at several lysine residues (Guo‚ 2007). This PTM might be to regulate gene expression (Feng et al.‚ 2010)‚ although
