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.
This process is called electrophoresis and helps us to better understand and identify the molecular components of living things. Forensics In the world of forensics, gel electrophoresis is used to obtain a DNA fingerprint of a criminal. This means that scientists can accurately tell whether two pieces of DNA, one found at a crime scene and one belonging to a suspect, are matches. Molecular Biology Microbiologists use gel electrophoresis on a regular basis.
