DNA Extraction

Before this lesson, I have never thought of extracting DNA. I thought that DNA could only be extracted by using complicated machines in hospitals. It kind of surprised me when I knew that I could actually extract DNA ourselves.

My group carefully followed the procedures on the guideline sheet. The DNA extraction procedures were pretty easy to follow. But I found that the materials used were quite weird. There were soap and alcohol. I had never dreamed of using soap to extract DNA. They didn't seem to have any relationship. I think I need to do more research to find out why soap is needed to extract DNA.

After several minutes, a white thing appeared between the soap and the water layers. I couldn't believe that it was the DNA. I couldn't really tell what it was like. Many groups also succeeded in extracting the DNA. I was really happy that everyone had a chance to extract and look at it.

I really enjoyed the whole process. But I hoped that I could have the opportunity to look at the DNA under the microscope. I would love to take a look at the inside of the DNA.
