DNA extraction

In our science class, we did a DNA extraction. We did the extraction on animal and plant DNA. I did the plant extraction. First what I did in the plant extraction, was I got a tube filled with strawberry juice. Next I Got a mixture of ingredients such as salt and alchahol. Once I got the ingredients, I grabed each of them one by one and placed them into the strawberry juice and swirled, not shaked the ingredients around. After I swirled the ingredients around, I added another ingredient and without swirling or shaking, I left it there for about 5-10 minutes. Once ten minutes were up, I looked at the strawberry juice and I saw the strawberry plants DNA floating around.
