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.
Preparing the DNA for electrophoresis. 1  A dye is added to the sample of DNA prior to electrophoresis to increase the viscosity of the sample which will prevent it from floating out of the wells and so that the migration of the sample through the gel can be seen.
