DNA, or deoxyribonucleic acid, is found in the cells of all living things. The higher the concentration of alcohol the better it will work to make the DNA come out of the water solution. Compare the process. Answer Key for Strawberry DNA Lab Part I: Questions 1. They carry necessary information required to carry out different processes in the cell. • describe the significance of understanding cell composition Prepare DNA solution of 1 ng/ml from whole blood extraction protocol described above. The vacuole in an an animal cell is smaller in size, or absent. In this lab, students will break open the cells from strawberries or peaches and isolate the DNA from the cell nuclei. The animal cell structure is the most prominent in human cheek cells. A fun and fascinating laboratory activity not only shows students how to isolate human genomic DNA, it lets them create DNA necklaces they can actually wear. Consequently, all living cells contain DNA. Strawberries are octoploid, which means they have eight sets of chromosomes. DNA also controls all cellular activities through its role in protein synthesis. Prepare DNA solution of 1 ng/ml from whole blood extraction protocol described above. For example, each cell in the human body contains 46 chromosomes (or 46 DNA molecules). DNA Extraction - Genetics After this lab Procedure for DNA Extraction and Precipitation Steps 1 and 2: Collecting and breaking open cells To collect as many cheek cells as possible, you will gently chew the insides of your mouth for 30 seconds and then rinse your mouth with a small amount of water.
