Electrophoresis and DNA Sequencing Many things have impacted both the Science and Medical fields of study. Electrophoresis and DNA Sequencing are two of these things. Together they have simultaneously impacted both of these fields. On one hand, there is Electrophoresis. Electrophoresis is a specific method of separating molecules by their size through the application of an electric field. It causes molecules to migrate at a rate and distance dependent on their size. On the other hand, there is DNA Sequencing. DNA Sequencing is a technique used to determine the exact sequence of bases

During this time, it could only be used in a lab with semi-intense supervision. Now, fast forward a few decades and there are D.I.Y. at home kits. The process of Electrophoresis starts with an electric current being run through a gel containing the molecules of interest. The molecules will then travel through the gel in different directions and speeds, based on their size and charge, allowing them to be separated from each other. Dyes, fluorescent tags, and radioactive labels can all enable the molecules on the gel to be seen after they have been separated. Because of these identification markers, they appear as a band across the top of the gel. Electrophoresis can be used for many different things. It is used to identify and study DNA or DNA fragments, and helps us to better understand the molecular components of both living and deceased organisms. Electrophoresis can also be used to test for genes related to specific diseases and life altering diagnoses such as Multiple Sclerosis, Down’s Syndrome, kidney disease, and some types of cancer. Electrophoresis also plays a major role in the testing of antibiotics. It can be used to determine the purity and concentration of one specific type of antibiotic or several general antibiotics at a time. Electrophoresis is also extremely useful in the creation and testing of
