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.
In the early days of DNA manipulation, DNA fragments were laboriously separated by gravity. In the 1970s, the powerful tool of DNA gel electrophoresis was developed. This process uses electricity to separate DNA fragments by size as they migrate through a gel matrix.
