EXTRACTION OF DNA FROM ONIONS ABSTRACT The purpose of the experiment was to experience firsthand the isolation of DNA form a plant tissue without destroying its structure and sequence. A white onion was used for the experiment. After several processes‚ DNA isolate was the visible result. Different chemical tests were performed on the DNA isolate‚ namely: Dische Test‚ Murexide Test‚ Wheeler-Johnson test and Test for Phosphate. Visible results were then noted.

in a standard solution‚ by using Hydrochloric acid to neutralise it. This experiment involved using distilled water to dissolve the sodium carbonate until 250 ml of solution were made. I had to calculate‚ from the information provided‚ how much sodium carbonate to use in the making of the solution. Using the volume and concentration of the solution‚ I was able to calculate the moles of the solution (concentration x volume). Using the periodic table I was able to calculate the molar mass of sodium
