After participating in a Science Teachers' Workshop offered by Carolina Biological Supply called "Make a DNA Necklace, " I have created my own recipe for a DNA extraction buffer that generates the same results as the company. In fact, the DNA yields for my lab are much higher than the company's while saving me hundreds of dollars over the years. Here is my secret recipe contained in this lab, along with a series of Analysis and Discussion questions for the students. An answer sheet is provided.
Students love the fact its their own DNA. Some give their necklaces away as gifts to loved ones eg. Mother's Day or Valentine's Day!
