DNA Extraction Warm Up 2 - Quiz

Welcome to the electronic biology classroom of the 21st Century. This warm-up or bell ringer will test your background knowledge using the Wheat/Human DNA Extraction Experiment, karyotype Lessons, and karyotype Studies. You are permitted to have any of those documents out during the warm-up activity. This warm up permits you an unlimited number of attempts to increase learning and test-taking skills. As a bonus, each attempt randomly generates new questions and answers.
