Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule. As the third step is in process, questions about DNA replication are also addressed. Finally, the DNA strands are placed into tiny tubes and hung on necklaces for biologists to wear home! If you can obtain the tubes, this would be a unique and memorable enrichment.
