One of the most famous model organisms in the field of genetics is Drosophila melanogaster better known as the common fruit fly. Through his work with fruit flies Thomas Hunt Morgan made many discoveries about how genes interact as well as how certain traits can be sex-linked (appearing only on one type of sex chromosome). In class we did our own work with fruit flies using an interactive digital lab. Click on the fruit fly to go to the digital lab.
GOLD TAPE QUESTION (Activity)
This week's GTQ is actually an activity. Your task is to extract DNA at home. Follow the directions in the attached pdf or just follow along with this video then take a picture of yourself with your lab materials and your extracted DNA (you can be creative with how you take the picture) You will receive 2 pieces of gold tape for your picture/pictures and an additional piece of gold tape for a written conclusion to your lab. You can write about what you learned, what worked or what didn't, and how you think this technique might have additional uses other than just being a fun at home science activity. Good luck!
Ask/Check with your parents before you do this activity and always wear safety glasses and use safe lab procedures
