The purpose of this assignment is to introduce you to basic DNA extraction techniques by isolating and visualizing DNA from a banana. Although this exercise will be completed in your home, it is theoretically the same method scientists use in a laboratory setting to extract DNA from cells.
Open the link to the document to find the experimental procedure and instructions for extracting DNA from a banana. Once completed, you will submit a photograph of your final result, along with the answers to several questions included in the file.
Follow the detailed directions below:
- First, read the full instructions in the document, Isolating DNA From a Banana.docx (链接到外部网站。).
- Gather your supplies, most of which you may have at home already, others of which are readily available at local grocery stores or pharmacies.
- Collect the DNA. Take a photograph and answer the questions in the document.
- Save the document in .doc or .docx format. Name it as “Mod3-Activity-Your Initials.”
