Comparative Effects of Organic and Inorganic Substances in the Repair and Renaturation of DNA

Abstract: In this particular experiment, three creams are tested comparatively in DNA renaturation. They are Turmeric (organic), Patanjali (semi-organic) and Fair and lovely (synthetic). DNA is extracted from the buccal mucosal cells of nearly 30 students selected randomly of age group 18-20 years. DNA is left for denaturation. DNA renaturation kinetics is done using the above mentioned solvents (5 mL of 1 % solution in distilled water). Optical Density values were then calculated for each of the sample. It was seen that turmeric was the most effective one in renaturing DNA, followed by the creams of Patanjali and fair & lovely.
