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. INTRODUCTION DNA (deoxyribonucleic

If we track our ancestors‚ long way behind we will find the same parents in our genome identity. Miraculously‚ the remaining one tenth of the DNA sequence is the genome that makes us what we are and an identical around the globe. That one tenth percent changes our appearance between one another‚ behavior and understanding and makes us powerful or incompetent. Due to this‚ study of DNA and its applications has become more and more important hovering lot of attention to carry out DNA usages for identification

Carbohydrates have two major functions in plants and animals: they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose‚ and since glucose is a major cellular fuel‚ starch represents stored energy. The sugar can later be withdrawn by hydrolysis‚ which breaks the bonds between monomers. Animals‚ in turn‚ have enzymes that
