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.

Volatile oils are the odorous and volatile products of various plant and animal species. As they have a tendency to undergo evaporation on being exposed to the air even at an ambient temperature‚ they are invariably termed

of edible oil | | | Oil and fat have always been an essential part of the human diet because of the energy they provide. Obtaining oil and fat from plants is a characteristic of many ancient cultures. There is evidence of the cultivation of plants that produce vegetable oils such as poppy seed‚ rapeseed and linen even in the Stone Age.
