My averages of all three fruits range from a difference compared to the other fruit of 1.67, 0.33 and 2. The order in which the procedure is stated is very important because the cells must first be broken down in order to release the DNA to be seen. and animals have DNA (deoxyribonucleic acid). Materials for each group of students: Look over some of the links provided and develop a hypothesis and design an experiment that will allow you to perform your own DNA extraction. Seeing DNA. DNA provides a blueprint for an organism's growth and development. It holds the instructions necessary for the organism to grow and function, and is passed on from generation to generation through heredity. When subjected to certain conditions, it is possible to collect large amounts of DNA to make it visible. Altering Animals. These instructions are in segments of DNA called genes.
