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.
1 Bio 210A DNA Gel Electrophoresis Purpose â¢ To learn the scientific basis of DNA gel electrophoresis. â¢ To learn how to pour agarose gels. â¢ To separate DNA fragments by gel electrophoresis. â¢ To analyze the size DNA fragments using a standard molecular weight marker. Introduction Agarose gel electrophoresis is widely used in biotechnology for analysis of DNA and RNA. This technique separates molecules based upon charge, size and shape.
