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. Electrophoresis is a common lab technique used to identify, quantify, and purify nucleic acid fragments. Samples are loaded into wells of an agarose or acrylamide gel and subjected to an electric field, causing the negatively charged nucleic acids to move toward the positive electrode.
