DNA Extraction Warm Up 1

Welcome to the electronic biology classroom of the 21st Century. This biology warm-up or bell ringer concentrates on the extraction and observing of DNA taken from wheat germ, strawberry and human epithelial tissues. I hope you read the EXPERIMENT: DNA Extraction Techniques! This laboratory warm up will permit you unlimited number of attempts to improve your test-taking and learning skills in advanced biology. As a bonus, each attempt will randomly generate new questions and answers.
