Drink apple cider vinegar with water, tea or juice to potentially reduce high blood pressure, a contributing factor in heart disease. 1  Studies have shown that rats responded positively to the acetic acid.
We will use agarose gel electrophoresis to determine DNA fragment sizes, and to quantify DNA. This technique separates DNA molecules based on size. DNA has a net negative charge that is proportional to its size. When placed in a matrix of agarose and exposed to an electric field, DNA molecules will move towards the positive electrode.
DNA electrophoresis is a method used to sort DNA molecules by length. Pieces of DNA are suspended in a tray of gel and subjected to an electric field, which causes them to migrate toward one end of the tray. The DNA separates out into bands, with the distance from the electrode corresponding to length of the strand.
